all day and the displays will be 

a f^reat attraction in themselves 

and will keep the crowds quiet 

and contented, when for any 

reason the aeroplanes cannot fly.

Gentlemen:^! have your letter of June 1st and thank you for your complimentary 
expressions. 

The Palmer Tires, with which I equip all of my aeroplanes give the best of 
satisfaction for the purpose. The light weight does not greatly impede the lifting 
power of the machine and the great resiUency enables me to land without shock on 
the hardest ground and to pick up speed quickly in starting. I am glad to credit a 
part of the success of my aeroplane to the Palmer tire. 

Yours very truly,

GLENN GURTISS AT IN^^^OOD-

HE USED A BOSCH MAGNETO 



m 



I icAeronautics 



MY object in undertaking aeronautical ex- 
periments has been purely from the 
standpoint of sport. In this I must say 
that I have not been disappointed. I and my 
friends have certainly found in it more out- 
door sport and interest than in anything else I 
have attempted in the past. Up to the time 
I sprained my ankle by a foolish attempt to 
beat a previous record, I made flights several 
times a week, or whenever the breeze was fair. 
There is not the slightest doubt that "flying" 
is the great coming sport. From my experi- 
ence I believe that the younger class of people 
who enjoy outdoor life will buy gliders and 
motor planes, and arrangements will be made 
so that the machines can be kept and used at 
the country clubs and the golf clubs, to one 
of which most of us now belong. At these 
country anrl gnlf clubs there is most always a

Gliding as a Sport 

By Hiram Percy Maxim 



Towed in this manner, the machine rises beau- 
tifully. It is absolutely steady, and when one 
gets thirty or forty feet above the ground 
there is usually found enough wind to keep 
one aloft without the tow having to advance. 
After becoming acquainted with the machine 
and the balancing and controlling, the tow 
lines are left off, and flights are made by run- 
ning with the machine down a hill against the 
wind. .After running aliout ten or fifteen feet 




corps of servants to look after a machine, and 
do the necessary repairing and refitting. In 
addition, these clubs always have splendid 
grounds upon which to practice flying. There 
are always hills for gliding, and in most cases 
there are large areas free from trees and 
similar obstructions. A great advantage is 
that in clubs of this nature the general public 
would not have access, and one would be able 
to begin his practice, which is always very 
clumsy, without having the invariable "gallery" 
of hangers-on, which is unavoidable at any 
public field. 

The illustration shows my Wittemann glider, 
which is really a very superb piece of work, 
being towed by a man against a breeze which 
probably was about fifteen miles per hour. 



a lift on the front of the machine carries one 
straight up into the air, and it is possible to 
coast down to and beyond the bottom of the 
hill, very similar to one coasting down a hill 
on a toboggan in the winter time. The greater 
the skill and the better the breeze the farther 
the coast. Indeed, I am wondering if with 
enough skill and breeze it would not be pos- 
sible to actually keep aloft indefinitely. If this 
were possible it certainly would open up great 
things. 

The accident which I was unfortunate 
enough to suft'er was due to carelessness on 
my own part. For the benefit of those who 
may also be so intoxicated by this most fasci- 
nating of all sports as to act foolishly, my ex- 
perience may be worth noting; 



AERONAUTICS 

I had made several very successful flights, 
being towed by an automobile against a breeze 
which did not amount to more than five or 
six miles per hour. Just at sundown I decided 
to make a new form of bridle hitch, and by 
the time I had completed it it had grown quite 
dark and the wind had fallen just short of a 
flat calm. Of course, it was no time to at- 
tempt to glide, and had it not been for the 
enthusiasm which this sport arouses I would 
have stopped. I told the driver of the auto- 
mobile to give me as near 20 miles an hour 
as he could judge in the dark. At the rear 
of the automobile we had fastened a 15-ft. 
length of 2-in. by 4-in. spruce. From the 
ends of this two tow lines were run, one to 
each end of the glider. After starting I 
rose quickly to about 50 ft., and in the ex- 
citement the driver of the automobile veered 
slightly from the true course. This meant con- 
siderable variation at the ends of the 15-ft. 



July, ipio 

timber at the back of the car. The result 
was that my starboard tow line became very 
taut, while my port line became slacked. This 
pulling on one side immediately tipped the 
glider up. I corrected this, but in the swing- 
ing sideways, due to the elevation, it suddenly 
brought the taut line to the other side. This 
gave me a sudden reversal of the dip, which 
was of such terrific magnitude that I could 
not begin to control it. The result was that 
the planes actually tipped up until they were 
standing straight up and down in the air. 
The machine then, of course, dove sidewise, 
and the result was a sprained ankle, knee and 
hip joint for the too enthusiastic writer. 

The moral is not to attempt these things 
unless it is light enough for the automobile 
to hold a straight course, and also unless 
there is a little breeze. In the free flights 
down hill there is practically no danger of 
accident to anyone having ordinary dexterity. 



Can a Man Fly 
With Wings? 

By H. La V. Twining 

[Continued from the June Number] 



President Aero Club of California : Head of Physics 

and Electrical Engineering in the Los Angeles 

Polytechnic High School ; Author of 

"Wi7-eless Telegraphy." Etc. 

A superfi.cial observation of the bird brings 
out the following facts : The wing is attached 
by its front edge forward and above the 
center of gravity of the body of the bird ; and 
the center of gravity of the body and the 
center of figure of the two wings are situated 
in nearly the same vertical plane. This rela- 
tion is fundamental. 

The pectoral muscles that lower the wing 
arc attached to the front edge of the wing 



muscles. The muscles that elevate and de- 
press the wing therefore oppose one another. 
This makes a lever of the third class of the 
wing, whereby power is converted into speed, 
forming a lever similar to the arm, at the el- 
bow. 

In Fig. I, let A be the body of the bird, B 
the large pectoral muscle, D the hinge joint, 
and E the elevator muscle. In this lever, for 
striking the air D is the fulcrum, E and B 
the power, while C is the long arm to receive 
a long and swift sweep. Consequently, d; 
short and powerful contraction of the muscle 
B resulting in a small movement at O throws 
the end of the wing C, through a long dis- 
tance quickly. Since the reaction of the air 
upon the wing C is proportional to the square 
of the speed with which it is driven, we can 
see at once the advantage of this arrangement. 
Here is a factor that makes the length of the 
wing much more effective than its width. In 
fact the wing must be narrow and long in or- 
der to develop the greatest reaction, and it is 
not a mere matter of the relation between 
square surface and weight with which we 
have to deal. The less the surface and the 




near the body, and the elevator muscles are 
found underneath the large pectoral muscles. 
They send a tendon up around the hinged 
joint between the wing and shoulder. This 
tendon attaches to the upper front edge 
of the wing, nearer the joint than does the 
lower rnuscle. The remarkable fact to be 
noticed is that the elevator muscles are very 
small and weak compared with the depressor 



shorter the wing, the greater the speed with 
which it must be driven in order to develop the 
same reaction. The wider the wing and the 
shorter it is, the square surface remaining 
the same, the faster it must be driven in order 
to develop the same lift. The longer the wing, 
the slower it can be driven in order to de- 
velop the same lift. In fact, its speed will 
vary inversely as the square of its length and 



AERONAUTICS 



July, ipio 



inversely as its width. It is readily seen that 
it is the outer end of the wing that really 
does the work. In fact, the inner part of 
the wing can be entirely cut away, and it 
will remain just about as effective. Either in 
soaring or in flapping flight, it is the end of 
the wing that is the most effective. 

The next feature to be noted is this : In or- 
der to obtain support a lo-lb. turkey must 
develop 5 lbs. reaction under each wing. 

We shall suppose that this 5 lbs. reaction to 
exist at the center of pressure which we shall 
suppose to be two-thirds of the way out 
towards the tip, at least. Since the pressure 
increases with the square of the distance from 
the center of motion, this is very nearly true. 
The turkey that I mentioned before has a wing 
spread of 5 ft., with an area of 3 sq. ft., 
and an average width of 71/2 in. This would 
locate the center of pressure about 20 in. out 
from the shoulder. The pectoral muscle that 
depresses the wing is attached about iH i"- 
from the shoulder. Here an important point 
presents itself. In a lever, the power times 
the power distance equals the weight times the 
weight distance. In Fig. i, if we regard 
the power applied at O as represented by X, 
D being the fulcrum, the power distance is 
OD. The reaction, which is equivalent to the 
weight, is at M and hence MD is the weight 
distance. QD is i^ in., MD is 20 in. and the 
reaction at M is S lbs., hence (X) (i^) 
equals (20) (5). Solving X, equals 66S lbs. 

If the above analysis be correct, then the 
turkey must pull with a force of 663 lbs. on 
each wing in order to fly. if it is continuously 
to support its weight. That is to say the 
turkey must maintain a pull of 133J lbs., 
while flying or soaring, provided it is con- 
tinually supporting its weight. 

This means the expenditure of .24 h. p. in 
order to rise i ft. in i sec. or .12 of a h. p. 
to rise 6 in. per sec. 

This is preposterous. A man's rate of work 
is about .1 h. p. If a man climbs a moun- 
tain, rising at the rate of a foot per second 
he has to be a hustler. This requires .27 h. p. 
In fact to go upstairs at that rate will take 
the breath out of an ordinary man. If he 
climbs at the rate of 6 in. per sec. he will 
be doing pretty well. This is .13 h. p. A 
lo-lb. turkey is not very fond of flying. A tur- 
key buzzard, however, weighing 4 lbs. and 
having a wing expanse of 3 ft. and an average 
width of 8 in. flies and soars with ease. Each 
wing is iy> it. long. This gives an area of i 
sq. ft. per wing, or 2 sq. ft. 

In this wing then we have: (X) (i) equals 
(2) (12) ; the pectoral muscle attaches i in. 
from the shoulder; and 5 of 18 in. is 12 in.; 
a 2-lb. reaction is necessary at M. Con- 
sequently X equals 24. Hence the buz- 
zard must pull 24 lbs. on each wing or 48 lbs. 
in all. This gives the turkey buzzard about 
.T h. p. to rise i ft. per sec, whether soaring 
or flying. 

An ordinary man weighs 37V2 times as 
much as the turkey buzzard, and if the buz- 



zard is expending energy at the same rate that 
a man expends energy, then it has to burn 
as much fuel as a man in a stove 1/37 as 
large. This does not look good to a reason- 
able mind, and there must be some mistake 
in it. 

If, on the other hand, the fulcrum is not 
at D, Fig. I, after the resistance of 2 lbs. 
is developed at M, but at M instead, then 
we have an entirely different proposition. 
In a lever the fulcrum is at the point of sup- 
port when the weight is lifted. When the 
bird is lifted by the reaction of the air, it is 
resting on the center of pressure of the wing. 
Hence the fulcrum ought to be found at that 
point. If this supposition be true, then the 
weight arm and the power arm are very 
nearly equal. MD is the weight arm and MO 
is the power arm. Then (20) (5) equals 
(18.5) (X) whence X equals very nearly 5.4, 
in the case of the turkey. In the case of the 
buzzard X equals 2.18 lbs. 

This shows that a bird in flying has to lift 
practically its own weight only. This looks 
more reasonable. This represents .02 h. p. 
for the turkey and .008 h. p. for the buz- 
zard in rising i ft. per sec. 

There are losses to be taken into account 
here, of course, that would increase this. 

But the question is, is the fulcrum really 
out at the center of pressure on the wing? 
Experiment only can determine it, although 
to suppose otherwise does violence to the 
judgment. 

In a recent experiment results were ob- 
tained, which point clearly to the conclusion 
that the fulcrum is really out at the center 
of pressure. 

EXPERIMENTS WITH MACHINE. 

Last sum.mer I constructed a machine built 
on the principles of bird flight as I see it. 
The machine weighs about 100 lbs. My 
weight is 140 lbs., making 240 lbs. The wings 
are manually operated by levers, which attach 
to the front edge of the wings through links, 
giving a leverage of four to one. The links 
attach 3 in. from the shoulder of the ma- 
chine. The point of attachment is thus located 
forward and above the center of gravity of the 
body and machine. The machine is mounted 
on three bicycle wheels. I had hoped to cause 
it to run along the ground when the wings 
were made to oscillate, and after getting up a 
speed of 8 or 10 miles per hour on the ground, 
I hoped to be able to develop enough lift to 
take it off the ground. But nothing of the 
kind happened. I could beat the wings some 
52 half beats per min., and develop enough 
reaction to take the wind out of me in about 
TO sec. The wings had 30 sq. ft. each of sur- 
face and were some 10 ft. long by 4 ft. wide 
at the widest part. It took only a one pound 
and a half pull to move the machine along 
the ground with myself in it. 

We suspended the machine by a block and 
pulley attached to a spring balance, and with 
myself in it, it weighed 240 lbs. By beating 
the wings down the machine rose 2 in. and gave 



AERONAUTICS 



July, ipio 



a i20-lb. lift on the scale. On the up stroke 
the machine rose slightly and developed for- 
ward motion. 

Now if the fulcrum is at the shoulder we 
have the following: OD, Fig. i, is 3 in., DM 
is 80 in., hence (3) (X) equals (120) (80) or 
X equals 3,200 lbs. That is it would take a 
pull of 3,200 lbs. at O to develop a reaction 
of 120 lbs. at M on both wings in order 
to lift the machine. It would take one-half of 
3,200 lbs. or 1,600 lbs. to develop 60 lbs. at 
M in order to lift half of the weight. 

As a matter of fact I was lifting half of 
the machine by making a 200-lb. pull at O. If 



the fulcrum were at D, I should have been 
able to have developed only a 9-lb. lift in- 
stead of 200 lbs. lift. 

By an i8-in. motion between the hands and 
feet, the tip of the wings can be swung 
through 10 ft. The above results seem to in- 
dicate that the fulcrum is out on the wing, 
and if that is the case, there is no reason 
why flight with wings should be impossible. 

There are other factors though that might 
favor or prove unfavorable to the above con- 
clusion. If the wing is wasteful of power, 
or if the power is applied in a very disadvan- 
tageous manner, it might still be impossible.

Curtiss' Flight Gets New Prizes. 

The Albany-New York flight of Curtiss imme- 
diately had its effect on prize giving. For the 
past two years newspapers have been asked to 
offer prizes, but they seemed very cold. Mr. Cur- 
tiss' flight seemed to work wonders over night. 

World-Post-Dispatch $30,000. 

At the Hotel Astor hancinet the .$."0.(100 prize 
of the New York World and the St. Louis Post- 
Dispaich for a flight from New York to St. Louis, 
was made public. Conditions have not yet been 
named, as the prize will, it is expected, be award- 
ed under the rules to be formulated by the national 
federation at its convention on, June 22. 

N, Y. Times-Chicago Post Prize. 

Another big prize of .$2.5,000 was announced at 
the Astor dinner by the New York Times in con- 
junction with the Chicago Evening Post, for a 
flight between Chicago and New York, about 9G0 
miles. Other prizes will undoubtedly be offered by 
cities along the route. Conditions for this also 
will wait for the national federation which, no 
doubt, will in the future control all events in this 
country of local or national character. 

Missouri Raising $10,000 Prize. 

Only a few thousand dollars is needed to com 
plete the prize of $10, 000 which will be offeree 
in July for a trans-state flight in Missouri, thi' 
start being St. Louis and the finish Kansas City. 
The prize will be open for competition the week of 
July 18, according to the present plan. 

It is further planned to allow five stops at as 
man.y controls, if more than one entity is received 
and to start all at the same time on a day to be 
specified by an impartial committee, which will 
take weather conditions and the preparedness of 
the contestant into consideration. Three days will 
be allowed for the journey. 

The course will probably be along the Wabash 
railroad to Kansas City, a distance of about 2T(' 

Edwin Gould Prize. 

Edwin Goul- -.*s offered through the ^scientific 
'merican a prize of $15,000 for the production of 



the best successful aeroplane equipped with two 
or more motors and two or more propellers, so that 
any power plant can be used either individually 
or in conjunction with the other or others. This 
prize is to stimulate the invention of a "safe" 
machine. The conditions will be announced later. 

Evening World Trophy. 

The Evening World has offered' a perpetual chal- 
lenge trophy in silver to the amateur making the 
longest continuous flight in any year. Each win- 
ner holds the cup for a year. The complete rules 
will be formulated and adopted at the national 
convention on June 22nd. 

Scientific American $100 Prize. 

The Scicntilic American offers .$100 in three 
prizes to be awarded to the inventor who gives 
the best account of how he conceived his inven- 
tion, how he developed it in actual practice and 
how he succeeded in, getting it. This sum is 
divided $50, $35 and $15, open to August 15th, 
1010. For rules address Scientific American, 361 
Broadway, New York. 



$20,000 for Race Between Wright and 
Curtiss. 

The Aero Club of Washington has offered $20,000 
to the Wrights for a flight from New York to 
Washington if they will enter one of their ma- 
chines against a Curtiss. 

J. P. Erie, of Denver, Colo., has been ex- 
perimenting with a glider in which the upper 
surface is some 8 ft. greater in spread than 
the lower. This, he says, lends greater stabil- 
ity. There are triangular "wing tips" from 
the upper to the lower surface, at an angle of 
about 45 deg. from the horizontal. 



First College Aero Degree. 

The first degree to be awarded l)y an .\merican 
University for work in' Aeronautics wa^s granted 
at the Columbia University commencement this 
June, when, Grover C. Loening received the degree 
of Master of Arts. Loening's thesis, entitled 
"An Investigation of the Practice and Theory of 
Aviation," is about forty thousand words long, and 
is a complete study of the aeroplane, from prac- 
tical as well as theoretical standftoints. Twenty- 
six large plates accompanying the thesis, and show 
details of the various successful aeroplanes.

§ How to Make I 
ill a Propeller :: |:| 



To make a propeller templets for a uniform 
pitch propeller, using the Drzwiecki method, 
one follows the plan below, which has been 
adapted from the French of M. Drzwiecki's book. 
You can take the pitch and diameter you have fig- 
ured out yourself, or take the dliameter and pitch 
of such propellers as mentioned in Aeronautics. 

First obtain the pitch constant M, i. e., Pitch 
divided by two times 3.14159265, or roughly, 
pitch divided by 6-2/7, or L as it is near 
enough. * 

Having obtained your pitch constant M, lay it 
out on the horizontal line AC (sketch I). This 
will give you the distance EB. Draw a line iiF 
perpendicular to AC from the point E. On this, 
starting from E, mark off lengths equal to %M, M, 
2M, 3M, 4M, 5M, giving you the points 1, 2, 3, 
4, 5, 6. Lines are then drawn through these 
from the point B. 

From these points 1, 2, 3, etc., with a radius 
equal to % of the specific width of the blade 
(This width is the width of the proposed propeller 
at that point and may be any width you choose.) 
arcs are drawn to intersect the lines IB, 2B, etc., 
on tlie same side of the vertical line EF as the 
point B. Lines parallel to AC are then di-awn 
through these points of intersection of the arcs 
with IB, etc. 

The same procedure is carried out on the other 
side of the vertical axis E'F, with the same cen- 
ters, but with a radius equal to % of the specific 
width and lines parallel to AC are again drawn 
through the points where these arcs cut the lines 
IB, 2B, etc.

AERONAUTICS 

The fourth sides of the templets are bounded 
by the vertical axis AD drawn perpendicular to AC 
at any optional distance from the point E. Drzwiec 
ki used narrow blades about one-tenth of the di 
ameter wide. 

The templets thus obtained are cut out of thin 
pieces of wood and the points "a" are marked upon 
them at a distance of Vi their width. The % of 
width point "a" is measured from the front edge 
of the blade, i. e., the same sidte as axis EF is on 
and directly under the axis EF. This is where the 
thickest point of the blade comes, or the shank 
in a metal blade, and is near the front, to be at 
or in front of the center of pressure. (See sketch 
I.) These templets are numbered as in sketch I and 
fastened to a board with their plane pei-pendicular 
to the board. All the points "a" are placed on 
the axis "xy" in sketch II. These templets are 
spaced %M, M, 2M, etc. The axis "xy" is di- 
rectly under EF. ^^ 

St. Louis Active in Ballooning. 

Charles F. Wenneker, president of the Million 
Club, has placed an order with H. Eugene Honey- 
well for a balloon of racing size, which S. Louis 
Von Phul will pilot in the elimination race to 
select the American team of three balloons to 
represent the United States in the international 
balloon race, which will start from St. Louis, Octo 
ber 17. The elimination race will be held Septeo; 
ber 17 from Indianapolis. 

This action on the part of the 
Million Club now makes certain 
five entries from the Aero Club of 



July, ipio 



Si. Louis in the elimination race, and gives the 
club a chance to win all three places on the Amcri 
can team. It is not expected that any other clu' 
will enter more than three balloons in the elimina 
tion race. 

These templets, of course, may be curved' to 
form segments of a circle. It will be seen that 
the inclined edges of the templets form a guide 
to determine the shape of the blade of the pro- 
peller. 

, 'Tfor illustration, take a Curtiss 6-ft. diam. and 
5-ft. pitch propeller, 4 in. wide at hub, 7 in. at ex- 
tremity. (Sketch III.) One blade is 3 ft. from the 
center of the hub. Draw a line 3 ft. long. Pitch is 
QO in. One-sixth of 60 is 10 in. Lay off 10 in. on 
line EC. Then take distances, 5":=y2M, 10"=::M. 
etc. This gives only four templets, due to 
the fact that Curtiss" propeller is shorter than 
Di-zwiecki's standard length. (Accord'ing to 
Drzwiecki, a propeller with a 5-ft- uitch ought to 



This will -duplicate, how- 
is it is not of uni- 



be about lOO in. long.) 
ever, a Curtiss' propeller, 
form pitch. 

The balloons piloted by members of the St. Louis 
club will be the club aerostats, St. Louis No. 3

and St. Louis No. 4, the latter just completed by 
Honeywell ; the Centennial, of Honeywell ; William 
F. Assmann's balloon, not yet christened, and the 
Million Club balloon. 

Wooster Lambert says he will be Honeywell's 
aid in the Centennial, unless the health of J. W. 
Tolland, who was to have filled the place, improves 
sulBciently to permit him to take part. The St. 
Louis No. 3 will probably be piloted by James 
W. Bemis, while A. B. Lambert may be the pilot 
of St. Louis No. 4.

Sunday. May 29. The Hudson-Fulton Celehra- 
tion of la.st October was made complete only today 
when Glenn H. Curtis.s, bearing a letter from the 
Mayor of Albany to the Mayor of Xew York, won/- 
the Xew York World's $10,000 prize for the first ' 
man to fly from Albany to New York, with an 
allowance of two stops on the way. Curtiss made 
but one stop within the conditions of the prize. 

After waiting several days for favorable weather, 
the start was made from Van Rensselaer Island 
in the Hudson River, at Albany, at 7 :02 a. m. 
Circling over the lower part of the city, a minute 
later he crossed the line and was on his way to 
New York. * 

At New Baltimore, a special New *Y'ork Central 
train bearing Mrs. Curtiss. Mrs. .T. S. Fanciulli. 
.\ugustus Post, the official observer: .T. S. Fanciulli. 
Henry Kleckler. Mr. Curtiss" Chief Engineer: a 
committee from Curtiss" liome town of Hammonds- 
port and the newspaper men and photographers 
caught up with the aeroplane and kept pace with 
it as far as the first stop, near Poughkeepsie. 

The New York Central Railroad runs close along 
the river as far as Spuyten Duyvil and the pas- 
sengers could see practically every foot of Cur- 
tiss" flight. 

FIRST L.VXDIXG .\T POtGII KEEPSIE. 

On down the Hudson without a skip of the en- 
gine, high over the Poughkeepsie Bridge he came, 
landing for gasoline and oil at Camelot, a few- 
miles below Poughkeepsie at S :2Q. after flying 7144 
miles in 8-3 minutes, a speed of 51.5 miles an hour. 
The machine was in perfect condition, save for one 
stay wire which vibrated too much. This was 
remedied. .V farm had previously b. en selected

Curtiss Passing West Point 



Pictorial Neirs Co. 



At 9 :26 Kleckler, who had come down on the 
special train, started the propeller and Curtiss 
was off again on the second half of his journey. 

Passing through the Storm King Mountains, 
where the crew of the Ilendrik Hudson are said 
to play at bowls on stormy nights, Curtiss met 
with his only difficulties in the way of air cur- 
rents. Suddenly the air seemed to give wa.y be- 
neath the machine and it dropped like a plummet 
a few feet in the descending current. 

"At Storm King." Mr. Curtiss told Aeronautics, 
"I was flying high through the narrow gap in the 
mountains and I caught the down current on one 
side more than on the other, and I dropped thirty 
or forty feet very suddenly and sidleways. I had 
to shift the front control to get straightened out." 

LANDS IN NEW YORK. 

Making a wide detour toward the Jersey side of 
the river, he flew over the railroad bridge spanning 
Spuyten. Duyvil Creek and landed at 10 :35 on an 
open, field on Manhattan Island. Ilis oil tank was 
leaking and, though the conditions were fulfilled, 
he wanted to make the feat complete by continu- 
ing on to Governor's Island off the southern part 
of New York City, so he deemed it best to fill 
up with oil to make sure of the accomplishment. 
From Camelot to Spuyten Duyvil is 56% miles, 
time 69 minutes, or an average of 49.347 miles 
an hour, somewhat slower than the first half. 

This field sloped steeply to the creek and there 
was no room to get a running start, so the ma- 
chine was headpd down the steep, grassy pitch 
and was in the air in record distance at 11 :42. 
Out over the bridge again he went, between 
roughly wooded hills on either side and turned 
gouth down the Hudson, past Grant's tomb and 



over the plying excursion and ferry boats, the 
Statute of Liberty, to within a few feet of the 
shed which housed his macliine on Governor's 
Island during the IIudson-Fulton celebration. The 
exact time was not taken here, but has been 
put at 12 noon. At 49.3 miles an hour it would 
.iust about take from 11.42 to 12 noon to cover 
the 14.5 miles. 

As soon as the Curtiss party and the newspaper 
men could get to the battery they boarded the 
little government ferry which runs to Governor's 
Island. Mr. and Mrs. Curtiss embracedl and were 
then congratulated by the few who were lucky 
enough to get by the guards at the ferry. The 
Ilammondsport delegation and a committee from 
the Aeronautical Society were on hand to express 
their appreciation of the great feat. The Aero 
Club of America, under whose auspices the prize 
was donated, unfortunately neglected the formali- 
ties of such a momentous occasion. 

The party went to the Astor for luncheon and 
then proceeded to the World oflice where the check 
for $10,000 was handed Mr. Curtiss with a few 
congratulatory words on his achievement. 

TRIAL FLIGHTS. 

Previous to this memorable flight, Curiiss made 
several long flights at Ilammondsport over Lake 
Keuka. landing in the water, one of which lasted 
thirty-eight minutes. 

Mr. Curtiss also entei-ed for the Scientific Ameri- 
can trophy, and the first half of his trip counts 
as a record for this event. Mr. Curtiss won the 
cup on the only two previous trials. 

THE MACHINE. 

Nearly four pounds to the square foot were 
carried in the flight, the upper plane having a [

spread of 31 feet 3 inches, bein? extended 30 
inches on each side. The lower plane measured 
26 feet 3 inches. The front and rear horizontal? 
were about three inches wider than usual. Flat 
rubber bags had been, arranged below the outer 
pxtreinities of the under planes, wooden strips 
Deing fastened to the front and rear lateral beams 
forming the chord of the surface and in between 
(v-ere the rubber air liags. Two cylindrical metal 
tanks were also attached under the lower surfaces 
5n a line with the wheels, and the usual central 
■ikid had a wide board nailed to it on which was 
mother rubber bag as shown in the photo. The 
two tanks were left behind at Spuyten Duyvil. 
Tust in front of the front wheel, too, was a small 
nirved surface to act as a hydroplane in case of 
anding in the water. 

A Bosch magneto secured the efficiency of the 
!park and a special large El Arco radiator kept 
he 50 H. P. Curtiss 8 c.vlinder engine cool, and 
Vacuum oil did the lubricatint;-. The wheels are 
itted with Palmer tires and the planes are cov- 
■red with Bakl'win combination cloth. 

PAUr,HAN'S FLIGHT COMPARED. 

Paulhan took 4 hours 12 minutes elapsed time 
o cover 183 miles when he won the London 
flail's .fSO.OOO and made it in two stages of 
LIT and 66 miles each. The 117 miles were 
;overed in 2 :39, a rate of nearly 44 miles per 
lour. A night's sleep intervened and the remain- 
ng 66 miles were covered in 1 :23, a rate of nearly 
18 miles per hour. The average for the above 
vas 44 :3T miles per hour. Paulhan could have 



landed at almost any time and started again, 
whereas Curti.ss could not have started if he had 
had to land in the water and for the whole dis- 
tance there wa-s scarcely a suitable space for 
landing on the ground, as for nearly the entire 
way rocky, wooded bills with precipitous sides 
line the river. 

DI.XXERS TO CIRTISS. 

Tile following Tuesday evening a banqut't was 
given by the World at the Hotel Astor to Mr. 
Curtiss, presided over by Mayor Gaynor. to which 
invitations were sent by the commonplace tele- 
graph. Telegrams of congratulation from all over 
the world were read between courses. The speak- 
ers were : Mayor Gaynor, Hudson Maxim, president 
of the Aeronautical Society; Samuel 11. Valentine, 
vice-president Aero Club of America: Don Seitz, 
of the World : Hon. .James M. Beck, and Glenn 
Curtiss himself was prevailed upon to say a few 
words. 

On. .lunc 7th the X. Y. Press Club gave a dinner 
to Curtiss. President .John .\. Ilennessy presided 
and introduced the speakers with an abundant fund 
of humor. .T. Bernard Walker, editor of the Scien- 
tific American, announced the Edwin, Gould prize 
with appi'opriate remarks. William A. .Johnston, 
of the X. Y. World, announced a trophy of the 
Erenini) World for amateurs: both proffers ai'oused 
great enthusiasm. The other speakers were : G. H. 
Curtiss, Charles M. Manly, Lieut. Humphreys, 
late of the U. S. A.; L<'e S. Burridlge, Clifford B. 
Harmon, William .J. Hammer, and Rhinelander 
Waldo.

'^-^K.e 



Tes K. Hamilton flew fro^in 
New York to Philadelphia and back in a Curtiss 
biplane in just a trifle over eleven hours. This 
is the first round trip between large cities and he 
kept a schedule which had previously been pre- 
pared very closely. His average from New York 
to Philadelphia and return was 50.72 miles per 
hour. On his trip over he m^de 50.09 and re- 
turning, 51.34. A special train on the Pennsyl- 
vania railroad followed him nearly the entire dis- 
tance. 

Hamilton mad'e the first start from Governors 
Island at 7.11 A. M., but the propeller struck an 
obstruction, breaking one of the blad^es. Glenn 
H. Curtiss took the propeller from his Albany- 
New York machine, which fortunately was still 
housed on the island, and it was nuickly put on 
Haimilton's 'plane, and he prepared for the sec- 
ond start, which was made at 7 :36 A. M. He 
rose rapidly to a height of about two hundred 
feet and circled Governors Island, passing over 
his starting point and continued turning, until at 
7 :43 he actually started over New York Bay, 
out over the Statute of Liberty and straight for 
the high chimney of the Standard Oil Company 
at Bayonne. Heading then to the right over the 
Kill von KuU at a speed of about 45 miles per 
hour he flew straight over Elizabethport, where 
he came in sight of the special train which ac- 
companied him over the tracks of the Pennsyl- 
vania railroad. He passed through Trenton at 
8 :49 and landed in, Philadelphia at 9 :26, just 1 
hour and 43 minutes after starting. 

Returning from Philadelphia the start was made 
at 11 :33 A. M. and Trenton was passed at 12 :09 



P. M. Shortly after this point the motor began 
misfiring and he became confused by the rail- 
road tracks of the Pennsylvania railroad and the 
Baltimore & Ohio railroad. Following the latter 
to South Amboy, he then decided to make a land- 
ing and seeing what he supposed to be a meadow 
on the shores of the Raritan River, he descended, 
but found the ground was a marsh. The spark 
plugs were changed and a new propeller sent from 
Governors Island was put on the machine to re- 
place the one which he had which was broken in 
landing. The machine was carried from this wet 
ground.,, up, the bank to a roadway, and a new 
start was made from this narrow place at 6 :20 
P. M. and Goverjio,rs Island was reached at 6 :40, 
a little over eleven ^ours from the time of eaving. 
Bosch Magneto and Palmer tire< won ;ignin. The ladi 
ator was an A-Z. 

Other Flights in Curtiss Machines. 

On .Tunc 7th to 9th. ^Villard and Mars were 

at Topeka. Kan. In flying over a railroad train, 

the .aeroplane caught the suction from the last 

cfvr'.tand dropped to the ground, partially wreck- 

U'-iag it. Mars was uninjured. •"''^ 

On .Tune 12 at Springfield, Mo., Willard's en- 
gine failed him at a critical point, after making 
two good cross-country flights. In making a hasty 
descent Willard sustained cuts and Bruises and 
the machine was almost totally wrecked. 

.T. C. Mars and C. P. Willard gave exhibitions at 
.Toplin. Mo., May 28-31. Both Willard -and Mars 
did well the first two days. Rain-then intervened 
and "rain checks" were issued. On the 31st a 
new "stunt" was developed. 

PROPELLER HIT BY DULLET. 

Opening the program of tiie last day of flights, 
Charlie Willard launched out on a cross-country 
flight early in the afternoon. Straight across un 
even country he flew until he disappeared across 
the crest of a line of hills. When he did not 
return after an hour's wait, .1. C. Mars, the 
other aviator, set out to find him. Following the 
direction taken b.v Willard, Mars found him six 
miles from the aviation field, near Carl Junc- 
tion, Mo. Mars landed nearby and discovered 
that Willard's propeller had' been splintered by a 
rifle shot, from some person whose identity is un- 
known. Willard was at a height of 500 feet when 
the bullet .struck his machine. He landed with 
considerable difliculty. liarely escaping collision 
with a clump of trees. As soon as he discovered 
the nature of the accident Mars fiew back to the 
aviation field, explained the circumstances and an 
automobile carried a new propeller to Willard', 
Mars returning to him through the air. , 

Willard's machine repaired, both aviators fiew 
back to the aviation field and described figures 
in the air for an hour. 

Hamilton finished his engagement at Atlanta, 
where he made his usual highly spectacular flights 
over the Speedway and during the auto races, on 
May 7th. The day before he made cross-coim- 
try flight to Jonesboro, thirteen miles away, and 
return. 

.\t Augusta, Ga., on the 11th of May he aroused 
an enormous crowd to a high pitch of enthusiasm. 
From there he went to Jacksonville, Fla., for 
May 21-22. 

Willard flew in Alexandria. Va., May 14, for 
thirty minutes in a drizzling rain.

Wright Students Complete Training. 

Dayton. O.. June 11. — The Wright Company 
closed the Montgomery camp the last of May. As 
the pupils there had practically completed their 
training they were brought on to Hayton to help 
train the new men. Since that time, flying has 
been done in all kinds of weather and in winds 
running up to thirty-two miles an hour. The men 
are taking long glides, and in fact, are thoroughly 
familiarizing themselves with the operation of the 
machine under every possible condition. 

Some sensational flights have been made for alti- 
tude, gliding and short circles. Only a few days 
ago. .Tune 8th, Orville Wright was up to an alti- 
tude of al)out two thousand feet. When al)out 
a mile and a half or two miles away from the 
field he shut off the power and descended on ;in 
angle, and to avoid over-sliooting tlie mark, he had 
to make several large circles. This was certainly 
an inspiring sight.

to get into the air. The ground at the aviation 
training camp at Dayton is peat, which rises into 
uneven hummocks and makes what naturally would 
be thought a most objectionable surface to start 
or land on. Tlie Wright aeroplanes have no 
trouble, however. 

During the last ten days, more than, 161 flights 
have been made of a total duration of twenty 
hours. The meet at Indianapolis, June 13th to 
ISth, is making everyone hustle, the factory is 
turning out a machine a week, and the Exhibition 
Department has bookings already to keep at least 
twenty-five machines going in the fall.

The photograph shows the students putting the 
truck under a Wright aeroplane at the Montgom- 
ery, Ala., aviation training camp in preparation 
for starting a flight. The rail on which this rolls 
is in sections which may be handled easily and 
quickly placed in position. Unless it is found d(>- 
sirable to make a quick and short start, as in a 
restricted area, the tower and welglit are not used, 
but the machine travels along the rail with its 
own propelling force, gaining momentum until 
the aviator raises the elevating planes and the 
aeroplane rises in flight. The use of the rail 
makes it possible to start on short notice on almost 
any kind of ground affording sufficient open space 



Bishop Wkight Takes First Trip. 

On May 25th the Dayton Aeroplane Club was 
invited by the Wright Brothers to visit the grounds 
and witness the flights. Eight wore made, on one 
of which Orville Wright went up to 2,720 feet. In 
another flight Orville took his father for his first 
ride, remaining in the air for ten and one-half 
minutes. 'The last trip of tlie day was made by 
the two brothers together, for the first time. 

.\ committee has been appointed by the Aero- 
plane Club to ari'ang(> for a suitable memorial 
to the W-*"ights. The club will also purchase an 
aeroplane and has two sites in views for an aero- 
drome. The club now has over six huadred mem- 
bers.

Wright Machines Now Have Tails. 

The ilhistratioa herewith shows the tail now be- 
ing used at Dayton. This apparently is either 
under independent control of the operator or is 
connected by crossed wires to the front rudder and 
acts in conjunction with it. A rudd<?r of this na- 
ture, under the control of the aviator, has been 
added to some of the French Wright machines, and 
in the German, Wright machines a fixed horizontal 
surface, 12 ft. by 2 ft. is also located as shown. 

Lots of Flying at Mineola. 

Mineola, .June 11. — A lot of credit must be given 
to Clifford B. Harmon, who is the only amateur 
in the East, at least, who is doing much flying. 
Since he began flying at Mineola his aerial trips 
have become longer and longer and he has ventured 
forth in greater and greater breezes. He has had 
a couple of accidents of no very serious couse- 



Seymour, who bought A. P. Warner's Curti«s, 
claims that he finds it very difficult to turn to 
the right, which is in the opposite direction to 
that of the rotation of the propeller, and a larger 
circle must be made than, when turning to the 
left. The ailerons seem to have greater effect and 
stability is more easily maintained when turning 
to the left. In flying straightaway in calm air no 
turning movement of the aeroplane itself is no- 
ticed. 

Captain Baldwin, since the first of May, has had 
about twenty days" flying, beginning with just 
runs on the ground and getting up to a fifteen- 
minute flight. Captain Baldwin believes ini a low 
center of gravity and has his motor placed low 
down on the lower plane, driving his propeller by 
a chain. While he uses ailerons now, he will 
shortly put back his vertical fin on top of the 
u]ii)e!- surface.

FLIES 55 MINUTES. 

His best flight has Ix'en one of fifty-flve min- 
utes and no one took particular notice of the 
fact. A year ago this was about the record 
and the papers described in full detail everybody'i- 
aeroplane, even if on paper only. 

These accidents Mr. Harmon ascribes to lack 
of power in his seven cylinder Gnome motor. -He 
has sent abroad for new valve springs whicli he 
expects will mal<e everything all right again. An- 
other Farman machine will also be delivered t( 
him shortly. 

Joseph Seymour, the auto race driver, has made 
more than a hundred flights, from little jumps 
to one of twenty miniutes day before yesterday. 



Ifarry S. Harkness is comi<Teting a big shed to 
liouse his Antoinette. 

W. L. Fairchild has installed his Itequa-Gibson 
motor, and will be ready in a few days to give his 
his monoplane, which comprises some new features, 
a try-out. In the next issue we will be able to 
give full details of the machine. 

In the Aeronautical Society's shed. Prank Van 
Anden has a new biplane, W. .1. Diefenbach is still

monoplane is nearly ready for trial and Miss E. 
h. Todd has her machine there. Edwards ajid 
Edick have a Curtiss-type biplane with a motor 
of their own make installed. 

Francois Raiche, who built a Curtiss-type bi- 
plane for Daniel Frisbie. of Kochester, started to 
try it out on June 8th. The engine was cranked, 
Raiche got in the seat, touched the accelerator 



12 



AEkONAUTtCS 



July, ipio 



and — but the machine did not move. Raiche looked 
wonderingly around to see why it didn't go, but 
there was nothin" doin.' The machine was given 
a good strong push and it ran along for ten 
yards when the propeller came off and the crank- 
shaft broke in two. The engine has four cylin- 
ders, opposed, arranged horizontally. On a pre- 
vious trial of the engine, the cylinders broke. 

Hamilton Flying at Mineola. 

On the day of the Curtiss flight, Hamilton and 
his machine arrived in New York. Within a few 
days it was down at Mineola where Hamilton did 
some of his highly sensational flying for the 
benefit of the hundreds of people, automobile par- 
ties from New York, wealthly residents of nearby 
summer colonies, who are on hand daily now to 
watch the flights of Hamilton, Harmon, Seymour 
and Baldwin, and to look over the other machines 
being built there in the sheds and tents. 

Hamilton goes up to a height of several hun- 
dred feet and then makes a dive to the earth 
at an angle of nearly forty-five degrees. Within 
twimty-flve or thirty feet of the ground he shoves 
up his front control and the crowd breathes a 
sigh of relief at the safe and easy landing after 
the fearful dip. On only one occasion here has 
he carried a passenger. 

On June 5th Hamilton be^an covering the ma- 
chine anew with cloth, as the old material had 
become worn out with almost daily use in all 
kinds of weather, in preparation for the flight to 
Philadelphia, and on the 8th he made a trial flight 
with the new covering. 

FLIES 66 MINUTES. 

The weatner delayed Hamilton's projected flight 
to Philadelphia and the aeroplane was not ready 
at Governors Island till the afternoon of June 11. 
Toward evening Hamilton made a great flight of 
66 minutes, soaring and swooping like a gnll over 
the ferry boats plying the harbor, not landing 
until it was pitch dark. 

On Sunday, the iL'th, another flight was made 
in the drizzling rain of about ten minutes. 

STEVENS GIVES ADVICE TO FLYERS. 

X. Leo Stevens offers a valuable suggestion to 
aviators. He argues that aviators should carry 
with them on the machine on cross-country flights 
a spare propeller. This would add little weight 
to the machine and would certainly avoid delays 
dependent uiion the breaking of the propeller. 

Erickson Gets His Plane Off Ground. 

.Vfter experimenting for several months with 
two dift'ereut biplanes. Louis G. Erickson, of 
Springfield, Mass., Anally made good. On May IL* 
lie rose about ten feet in the air, traveled sixty 
feet or more at a very uncertain angle and then. 
slnit oft" the power just as it looked as if the bi- 
plane would turn completely over and bury the 
•wiator beneath its wreckage. On May 20' another 
trial was made, but no better results obtained. 

This is the second biplane Mr. Erickson has 
built. He is now working on another biplane, the 
planes of which will be 5x30 feet. The frame will 
he of spruce and bamboo, and the fabuic wii be 
rubberized silk instead of varnished cambric.

Flights at Plum Island. 

William Ililliard, an auto racer of Boston, has 
been making successful flights in a Herring-Bur- 
gess machine at the company's trial groimds at 
Plum Island. Mass. 

The Herring-Burgess aeroplane bought by C. W. 
Parker, a showman of Abilene. Kans., made its 
Hrst flight since the latter's ownership on May 20 
at Salina. Shortly after it left the ground it was 
struck by a gust of wind and LaComme, the inex- 
perienced pilot, shut off the motor. A couple of 
braces in tlie running gear were broken. 



Indianapolis Meet Opens. 

Indianapolis, June 15.— The second day of the meet 
closed yesterday. Five Wright aviators are here and in 
addition are: J. W. Curzon [Farinan], M. Marquette 
[Martiuette], ©, R. Shaw [Shaw], Lincoln Beacliey 
[Beachey] and G. L. Bunibaugb [Fisher]. 

Previous to the opening the Wright aviators made some 
preliminary asct nts. 

New World Altitude Record ? 

W. li. Brookins [Wright] flew to an altitude of 43S4 
feel. A conflrraation of this was .sought and the corrected 
height put at --'100 feet. There may be an error in the 
sending of one or the other of the messages. Orville 
Wright himself made a short flight. Brookins made ti 
miles for the fastest 10 mile prize. A. L. Welsli [Wright] 
made the mile trial in 'i-.Hi. Biookins gave a spectacular 
exhibition of tigures, sharp turns and a dive. Two ma- 
chines were in the air at once, each carrying a passenger 
for 12 minutes. 

Brookins [Wright] made a trial hit'li liiKht, going up to 
il)9i feet. In the seco!id trial he did even better, being 
measured at -ISSt feet by A. B. Lambert of the .St. Louis 
A. C. 

G. L Bumbaugh met with an accident in a machine of 
local make, after getting sixty feet in the air. Bum- 
baugh, the veteran balloonist and dirigible pilot, was 
caught under the machine w hen it fell, and painfully 
injured. 

Full details of the meet will appear in the next issue.

Bicycle Rider Turns Aviator. 

Charles W. Miller, the world famous six-day 
bicycle rider, says he expects to win the New York- 
St. Louis .$.30,000 prize. 

Mr. Miller has just had completed by Messrs C. 
and A. Wittemann, of Staten Island, an aeroplane 
of his own design, equipped with a 75 H. P. White- 
head motor, a comparatively new, high powered 
aviation motor. With this power Miller's aero- 



plane, which is of the biplane type, is expected 
to carry three. 

The main planes spread 35 ft., by 6% ft. fore 
and aft. These are covered with No. 6 Naiad 
cloth laced to frame and stretched to drumhead 
tightness. These are spaced 6 ft. apart. 

The steering is operated bv a wheel as in an 
automobile, somewhat similar to the Curtiss ar- 
rangement. The front elevator has an 8-ft. spread, 
by 2%-ft. depth. A double surface, self-balancing 
tail is provided for stability, with a single vertical 
rudder in the center. Vertical surfaces between 
the planes, similar to the Voisin machine, tend to 
maintain lateral equilibrium. The machine is 
trussed with steel aero cable, galvanizedi to pre- 
vent rusting, fastened to Wittemann turnbuckles 
and specially designed eye bolts.

The chassis is equipped with three pneumatic 
tired wheels, the rear wheels liaving a spring shock 
absorber, as shown in the June number. 

The ribs are three ply, laminated ash and 
spruce. The weight of the machine, complete, is 
760 pounds. The magneto is Bosch high tension 
radiator El Arco. 

The propeller of the Miller aeroplane is 8 ft. 
in diameter, of 6-ft. pitch. The Whitehead Com- 
pany reports that "On test it gave 270i poundte 
ilirust. but this l\v no meats utilized the power 
of the engine, the propeller being one that was 
merely calculated to drive the aeroplane about 
thirty-eight miles an hour. For higher speed's Mil- 
ler will carry different propellers. 

"On a preliminai-j' test, the engine with a 10-ft. 
propeller, with a T-ft. pitch, and IT-in. width of 
blades gave a thrust of 410 pounds. 

"This is the greatest thrust that has ever been 
developed by a single engine on a single screw

has a much deeper curve and Is set at a consid- 
erable angle. Lateral stability is maintained by 
the raising and lowering of the bottom planes, 
making thejB more or less effective. 

The gyroscopic force of the revolving cylinder 
motors also tend to keep the machine on an even 
Keel. When the machine was first put together 
there wrre two horizontal rudders, 6 ft. by 4 ft. 
•'! in. — one 14 ft. in front and the other the same 
distance in the rear, but after a few trials an- 
other surface was added to each rudder. The rear 
one was made stationary and the front one was 
moved to within 10 ft. of the main, cell. With 
this imjirovement the machine flew about lOO ft. 
at a height of 6 ft. The flight was stopped by the 
breaking of the tail. Owing to breakages, no 
more flights have been made. 

There are two revolving cylinders, .36 h. p. Ad- 
ams-Parwell engines, set one on each side of the

"The Whitehead motor in construction is of the 
utmost simplicity, there being no valves, springs, 
cams, cam shafts, rocking arms, or intake mani- 
folds. There is absolutely nothing to get out of 
order. The utility of the two-cycle type and its 
ability to make long runs without getting out of 
order is generally recognized. The Whitehead motor 
has reached a degree of perfection which has neve 
before been attained by this type of engine, and its 
lightness, only 200 pounds, makes it the leadin;; 
engine for aviation." 

The Andrews Biplane. 

E. P. Andrews, of Daytona Beach. Fla.. has 
built a biplane which has a wing spread of 4.". ft.. 
the top plane being about 4 ft. shorter than tln' 
bottom one. The planes are 7 ft. wide at tln' 
middle and 4 ft. 3 in. at the tips, and are 6 ft. 
apart. The top plane has a very small curve and 
appears to be set level, while the bottom plane

I)ropellers of 4 1^ ft. pitch. 

The machine weighs about 6O0 lbs. and is mount- 
ed on thri>e small wheels witliout springs. The 
horizontal and vertical rudders are controlled by 
two small wheels, one above the other, while the 
balancing planes are controlled by foot wires. 

Sails Over New York. 
New York, .Tune 14. — Fred Owens sailed his 6 
II. P. dirigible from Hillside Park, Newark, across 
.New York to-day. Passaic was crossed, then the 
Hudson Kiver to the City Hall. The engine got 
going bad and he attempted to land on the roof 
of the City Court Building. Someone in his zeal 
to help gral)b<>d \\\o trail rope and the airship hit 
the chimney, breaking the frame and stopping the 
motor. The shij) went up again in this condition 
and crossed the East River, narrowly missing the 
Brooklyn Bridge, to a safe, though precarious 
landing in a tree in Brooklyn, wh(>n he was res- 
cued by firemen.

The Loose Monoplane. 

GEORGE H. LOOSE, of the Pacific Aero Club, 
has just completed a new aeroplane which 
he is now trying out. 
The machine, 32 ft. spread, 31 ft. long, and 
7 ft. high, is noticeable for its bird-like lines. H 
is very well and strongly built, having a number 
of novel and original features, several of the con 
structural details being especially praiseworthy. 

Planes, in two halves, do not attach direct to 
body but join together a few inches above the in- 
verted triangular frame, where thev are held bv 



20" ; rims and tires appear rather too narrow, hub 
6". Steel tubing axle supports the two 28" by 
IV2" elliptic springs, one on each side. Eight 1", 
by 16 guage steel tubes, 4 on each side, branch 
from spring clips and support the bird-shaped body. 

Body. lYi" round spruce members connected 
with same ingenious patent fasteners, as shown in 
photo of former machine (Aeronautics for April 1 
form an inverted triangle ; the front carrying a 
special alloy casting which holds the front bear- 
ing (R. I. V.) of the propeller shaft, flns cast 
integral allow the frame members to be bolted to 
easting making a very rigid front bearing, the 
inner end of casting taking the thrust or pull 
bearings. Uprights, 35" apart, guyed with piano 
wire and turnbuckles of own make. Seat of alum- 
inum 2 ft. from ground, placed over lower frame 
member. Two wire-wrapped, steel-shod skids are 
placed at the rear extremity of the frame. 

Rudders and Keels. Horizontal rudders, Antoin 
ette type, front edge 18 ft. back frorp rear edge

rigid connections ; are 10 ft. deep at the joining 
and extend 16 ft. laterally, the depth of the curved 
ends being 7 ft. 6 in.; total surface 275 ft. 

Construction, double covered ribs, Vz in. by ^4 
in., 6 in. apart, 3 built-up lateral wing bars or 
beams, 1 in. by % in., with V2 in. blocks between. 
Curvature, arc of a circle, a little over 1 in 19, 
greatest depth at approximately center of plane. 

Incident angle on ground 9 degrees, flight about 
5 degrees. Three bamboo poles 12' 2" long, rein- 
forced with two wires, on each side, one behind 
the other in the plane of flight, take the weight 
and also a part of the lift of the planes, being 
fixed to the chassis at their lower ends in such a 
manner as to be easily removable in demounting 
wings. 

Momttinp. The novel idea of using full elliptic 
springs is, I believe, in this machine its first adap- 
tation to the aeroplane. Tread, 8 ft. ; wheels. 



main planes, 2 triangular surfaces 4 ft. wide 28 
in. deep, between which is a vertical rudider 44 in. 
high by 30 in. wide. These rudders are kept in 
their normal position by spiral springs. The en- 
tire rear rudder construction is of small steel 
tubing properly brazed. 

Keels, both horizontal and vertical- are in evi- 
dence, tapering down from size of rear rudders to 
a point 10 ft. therefrom on the frame and having 
about 40 sq. ft. in the horizontal and 34 sq. ft. 
in the vertical. 

Power Plant. In deference to Mr. Loose wishes, 
description of motor, further than it is a 4 cylin- 
der o%" by 4", 25 H. P., is withheld as is method 
of lateral control. The motor placed in front of 
and above operator drives by a short chain. The 
driving member is a 9" diameter 3^^" face cone 
clutch, mineral-tantted leather face. Gear ratio

2 to 1 of propeller. A rear propeller shaft bear- 
ing is affixed to the front of motor. In "Mount- 
ing" have given description of front and thrust 
bearings. A clutch lever extends to within reach 
of operator's seat. 

Propeller is 7% ft. diameter, 8 ft. pitch, but 
looks to be wasteful of power. R. P. M. stated 800. 

Radiator^ constructed of brass tubes 1%" wide. 
is of neat workmanship, specially built for this 
machine by the Pacific Radiator Company of San 
Francisco. It is of a triangular shape and fits into 



July, ipio 



the body frame-work over the motor, not increas- 
ing drift to an appreciable extent. It is doubtful 
to the writer if the comparatively high pitch 
speed, 8x800=6,400 ft., can be realized with the 
25 H. P. and 71/2 ft. diameter propeller. 

The weight of machine complete with operator 
and fuel for 10 miles is about 700 pounds, which 
compares favorably with the Bleriot XI, the lat- 
ter having 2.3 H. P. and 1.51 sq. ft. lifting sur- 
face. 

The body design, is ideal in allowing propeller 
shaft free passage. 



Miguel Lebrija has demonstrated that an aero- 
plane will fly in the altitude of Mexico City 
(7,500), and with a Bleriot monoplane he re- 
cently made fifteen successful flights on the plains 
of Valbuena. 

Starting from the hangar, Mr. Lebrija ascended 
to the height of sixty-five feet and successfully 
steered his machine around and around through 
the air, maintaining that height for five minutes 
when he descended. After receiving the congratu- 
lations of his many friends who witnessed the 
performance, Mr. Lebrija again mounted his seat 
and made fifteen more flights, all more or less 
of the same duration as the former. 

Machine Used 'Was A Bleriot Monoplane. 

The machine he used in his wonderful per- 
formance was a monoplane of the Bleriot type 
similar to the one used for the cross-channel flight 
by Bleriot and was not equipped with any special 
motor or attachments, but was simply a stock ma- 
chine as received from France. 

In starting the machine left the ground 200 
meters (666' 2") from the starting line and rose 
to a vertical height of about sixty-five feet, antf- 
during the many trials this height was not ex- 
ceeded by the aviator, but he stated that he could 
have gone much higher if he had so wished. 

Apparatus under Perfect Control. 

The monoplane was under perfect control and 
obeyed the rudder with ease and when landing 
glided gracefully to earth and stopped without any 
perceptible jar. No accident occurred during any 
of the flights and there was no dlSiculty experi- 
enced with the motor and Mr. Lebrija, by these 
flights has plainly demonstrated that heavier than 
air machines can be flown successfully in this alti- 
tude, and the former theory that this was impos- 
sible on account of the experiments made with a 
few buzzards brought from Veracruz which died, 
a few days after reaching here, was completely 
exploded. 

Yesterday Mr. Lebrija while trying out his ma- 
cliine, arose to the height of about thirty-flve 
feet, and maintained that height for about ten 
minutes to the delight of the numerous spectators 
that had gathered around to witness the flight. 

Mr. Lebrija while in the air stopped his motor 
and glided towards the ground, and when about 
fifteen feet from terra flrma, started the motor 
again and rose to a height of about seventy-five 
feet. Then stopping the motor he gracefully 
glided to the ground, making a safe landing. 
After this Mr. Lebrija made several other flights, 
all of which were successful. 



Flying in Mexico 

By E. L. Ramsey. 



Mexican Army Is to Have No Balloon Corps — War 
Department Denies Rumors to That Effect. 

For some time rumors have been current to 
the effect that the Mexican Army was going to 
be equipped with an Aerial Fleet for which pur- 
pose a number of Aeroplanes and Dirigible Bal- 
loons had been purchased and that the equipment 
would soon arrive in Mexico. 

These rumors were denied at the war depart- 
ment yesterday by Col. Luis Perez Figueroa, who 
stated there was no truth in the reports. Col. 
Figueroa said : 

"Some oflScers of the Mexican Army have been 
commissioned to study aviation in various coun- 
tries, but further than this, the war department 
has not taken any steps to equip the Mexican 
Army with Aeroplanes or Dirigible Balloons." 

An Aviation Treaty Between Mexico and the United 

States for the Proper Regulation of 

Emigration and Smuggling. 

The Mexican Ambassador in Washington, Sr. 
Francisco L. de la Barra and Secretary of State 
Knox, have been discussing a treaty between the 
United States and Mexico with regard to aerial 
navigation and which will have for Its purpose 
the enforcement of the treaties at present in force 
with regard to emigration and smuggling. 

The treaty which will be signed by Mexico and 
the United States will be the first of its nature In 
the world as up to date, while the several nations 
of the world have apparently become alarmed at 
the perils offered by aviation in the event of war. 
they have done nothing towards solving the prob- 
lem as regards the improper passage over frontier 
lines.

Tanforan Meet Held in Conjunction With 

Auto Races by the San Francisco 

Motor Club, 

Tlie Greene biplane belonj^ing to Roy Croslj.v. 
equipped with a new motor and liaving a number 
of clianges in. its m^alce-up. was brought out on 
the field at Tanforan, Cal., May 29th and .•JOth. 
but the wind was evidently too strong for the 
new aviator, Harold Hall, to buck against. Hall, 
who is only 18 years old, has mad« several flitjhls 
with this machine and also has flown Prank 
•lohnson's "Curtiss." 

The gliding contests attracted a large number of 
entries. All flights were towedl The two-rope way 
of towing is open to criticism, it being in the 
writer's opinion a dangerous method. 

Ten-year-old Walter Sittman won first prize of 
.$100 for height. Wolf and Becher won second. A 
novel feature was the flights by the three young 
Misses Johnson, one of whom won second prize. 

The second day the first prize was won by Har- 
old Winthrop ; second prize by .1. Sittman. the 
Becher and Wolf gliders winning three prizes. 

Robert Bergfeld, while being towed by two autos 
had a bad fall owing to a rope breaking. The 
glider was totally destroyed. Bergfeld having a 
lucky escape. 

Exhibition at San Jose. 

San, .Jose, Cal.. is tired of aviation and the pro- 
moters of the Anto and .Vero Show during the 
Rose Carnival, had a hot argument with Frank H. 



.Johnson, who has been giving none too sensa- 
tional exhibitions with his Curtiss machine. John- 
son is reported to insist on pay whether he flii^s 
or not. During the fete .Tohnson made one or 
two short flights and Harold Hall took Whipple 
Hall's Curtiss machine for a mile. 

University of Illinois Flights. 

The aviation '■meet" of the I'niversity of Illi- 
nois, at Uriiana. was a fizzle, all but the kites 
of Samuel F. Perkins, who had his usual big 
dis|ilay of kites to make good when the aero- 
l)lanes fail to fly. In. a preliminary flight the day 
l)efore the exhibition day, May 21. Otto Brodic 
considerably damaged the Curtiss aeroplane. The 
wreck was bixjught back to the university wood 
shops, and with the help of instructors, employes 
and students, was repaired late at night. Nothing 
more was done until the 23rd, when they took it 
out on the golf links. (In. the repairing different 
wood had been used, and it had been rained upon, 
soaking it and putting the machine out of bal- 
ance.) Brodie ran the machine several hundred 
yards, under power, on the ground, and then flew 
back to the starting point, liit a small sapling, and 
— two hours or so for repairs. Brodie or Wild 
made eleven starts, and once rose almost tw" 
feet off the ground and stayed up for almost thirty 
feet. So everyone came back in disgust and' the 
machine went back to Chicago the next day. 

The reasons ascribed to the failure of the event 
were : The unbalanced condition of the machine, 
and the ovei"weight. due to the soaking; the small- 
ness of the field, 400 or 450 yai'ds : the crowding 
of the spectators, and the possibility- of the engine 
being underpowered.

have signified their definite intention to partici- 
pate. The first entry came from William Thomas 
of Hammondsport. N. Y.. with his biplane, re-

came from William Curtiss Robinson, of Grinnel 
la. (monoplane), and from Eric Bergstrom. Chi- 
cago. HI., with what he claims is the smallest 
monoplane for its carrying capacity in the world. 
Howard Gill, of Los Angeles, Cal., entered a Gill

tary of the Aero Club of St. Louis, 304 North 
Fourth Street, St. Louis. 

The meeting was postponed in order to gain timr 
in which to obtain larger grounds to accommodate 
the number of machines of which entry was prom- 
ised. It is now expected that twenty planes will 
be on the field, and the construction of half tha. 
many sheds will be begun at once, others going ri] 
as entries are received. 

The new grounds will be sufflcieptly large for al 
inn-poses and will form the permanent aviation 
held of the Aero Club of St. Louis, to be known 
as Camp Xo. o. The Aeru Club has already es- 
tablished a small field within the city limits, where 
H. A. Robinson and J. X. Sparling are practicing 
with their nuichines. 

Aeroplanes Will Fly in Montreal. 

Montreal is giving evidence of her i)rogresslve 
spirit by announcing an aviation meet to take place 
there, commencing on the 25th of June and la^ 
ing until the 4th of July. 

The meet will be held under the auspices of the 
Automobile and Aero Club of Canada, which is 
affiliated with the mother institution in Great 
Britain, and is being organized by E. M. Wilcox, 
publisher of Mutoring, and C. W. Bennett, a well- 
known Canadian theatrical magnate. 

Five Wright machines will definitely fly and it is 
expected several others will participate. 

St. Louis to Hold Show. 

Under the auspices of the Aero Club of St.

outdoor aeroplane and balloon events will take 
place iu St. Louis, and is under the management; 
of G. L. Hoi ton,. 

The Aero Show will be a complete exhibition of 
things aeronautic, and will include displays of 
nearly every manufacturer of aerial apparatus 
and supplies in America, and agents for foreign 
makers. 

In. kindly offering free news service of the show, 
the promoters state : 

"The show has been organized with a serious 
purpose, which we believe will be apprecfated by 
the press of America, in that the object is to 
advance the American aeronautic industry so that 
it will compare favorably to the industry which 
alrcadv exists abroad."

AFFILIATED CLUBS REVOLT. 

Form New Organization. 

Resenting its deeds and misdeeds, its arrogant 
attitude, tlie lack of representation, so on and 
so forth, tialf of tlie affiliated clubs have formally 
cut the strings of the Aero Club of America's 
apron and will now shift for themselves as best 
they may. 

This happened at a meeting of the affiliated 
clubs called by the A. C. A. and held in its 
rooms on May 23. When the delegates were 
called to ordter in the morning there seemed to 
be no business to transact except to renew affilia- 
tion for another year and make any suggestions 
to the mother club which might or might not be 
acted upon in the discretion of the board of di- 
rectors. Someone moved to adjourn. 

Following were the delegates assembled : A. B. 
Lambert, Indianapolis and St. Louis ; Col. Jerome 
H. Joyce and A. Albert Hughes, Baltimore ; A. W. 
Carpenter, Harvard ; W. B. Strang and George M.-' 
Myers, Kansas City ; James E. Plew and Victor 
Lougheed, Chicago ; J. V. Martin, E. C. Brown 
and R. M. Allen, Harvard Aer'l Society ; J. S. 
Panciulli, Washington ; J. M. Sattei-fleld, Buffalo ; 
Alan R. Hawley, Pittsfleld, and Augustus Post, 
Canton. 

In the afternoon a second meeting was held. 
Samuel H. Valentine, the chairman of the morning 
meeting, Philip T. Dodge, Augustus Post and Alan 
R. Hawley, all of the A. C. A., withdrew at the 
second session, after granting the use of the club 
rooms. Jerome S. Fanciulli, representing the 
Washington Club could not officially represent that 
body at the afternoon meeting. 

A resolution was adopted calling for the organi- 
zation of the American Aeronautic Association, 
which was then formed with George M. Myers, 
Kansas City Aero Club, President ; A. B. Lambert, 
St. Louis Aero Club, First Vice-President; J. V. 
Martin, Harvard Aeronautical Society, Second Vice- 
President ; Victor Lougheed, Aero Club of Illinois, 
Secretary, and Col. Jerome H. Joyce, Aero Club 
of Baltimore, Treasurer. 

The reason for the new organization was de- 
fined in the following resolution, which was unani- 
mously adopted : 

"We recommend that for the administra- 
tion of Aeronautical afflairs, of national or 
local character in the United States, the 
American Aeronautical Association be formed 
at once, with officers elected to serve imtil 
June 22nd, 1910, in New York City, at 
which time we recommend that new officers 
be elected for the ensuing year. 

"We further recommend that all aero- 
nautical clubs and l)odies now existing or 
in the future to be organized in the United 
States, including the Aero Club of America, 



be invited to join this Association upon 
some acceptable basis of powers and repre- 
sentation, founded upon the numbers of 
such clubs, or upon their membership, in ac- 
cordance with rules and regulations to be 
enacted into permanent form by the repre- 
sentatives of affiliated clubs here assembled, 
and to be revised from time to time as may 
be decided at future meetings of the rep- 
resentatives or delegates of affiliated clubs." 
The following letter was delivered to the A. C. 
A. together with a copy of the resolutions printed 
above : 

"New York, May 23, 1910. 
"To the Aero Club of America, 
"29 West 39th Street, 
"New York City. 
"Gentlemen : 

"At the meeting held today by repre- 
sentatives of the affiliated aero clubs, as- 
sembled in response to your call at your 
headquarters, 29 West 39th Street, after 
discussion it was decided that the best in- 
terests of the affiliated clubs could not be 
advanced by conforming to the proposed 
arrangement between your organization and 
the Wright Company, and that the future 
of the affiliated clubs and the interests of 
aeronautical development in this country 
could be better conserved by a separate or- 
ganization, which would not be fettered by 
the entanglements now existing by reason 
of our connection with your organization. 

"The meeting was. therefore, adjourned 
without action, immediately after which the 
affiliated club representatives called a meet- 
ing for the purpose of organizing the Ameri- 
can Aeronautical Association, to be a demo- 
cratic organization, representative of the 
aeronautical interests of the entire United 
States, for the purpose of controlling aero- 
nautical events in this country. 

"In accordance with the expression of 
opinion in the foregoing resolution, you are 
cordially invited to send delegates to our 
next meeting. 

"In. closing we wish to extend our sincere 
thanks for the courtesies of your organi- 
zation. 

"Respectfully yours, 
"THE AMERICAN AERONAUTICAL 
"ASSOCIATION, 
"Per VICTOR LOUGHEED, 

"Secretary." 

New National Body Organizes June 22. 

On June 22 in New York there will be held 
a big convention with representatives from a 
large portion of the eighty-odd aero clubs in the 
country, at which time officers will be elected for 
the ensuing year, plans formulated for the work 
of the body, the adoption of rules governing con- 
tests and the various prize offerings now awaiting 
the action of the convention., etc. 

As announced in the last issue, the movement 
for a national body was started by the issuing of 
a letter by Hudson Maxim, president of The 
Aeronautical Society, to all the aero clubs of the 
country. This met with great response.

ARRONAUTtCS 

The day foliowing the secession of the A. C. A.'s 
clubs several meetings were held between, repre- 
sentatives of the newly formed American Aero- 
nautic Association, and of the Aeronautic Federa- 
tion of America with the result that the conven- 
tion of June 22 will be a joint affair comprising 
delegates from all the clubs with which corre- 
spondence has been had by both movements. 

At a meeting held on June 2 of the Aeronautic 
Fedei-ation of America a temporary committee was 
formed taking in members thereon appointed for 
this service by the various clubs associated with 
the federation. Some forty clubs are represented 
on this committee, which is headed by Professor 
David Todd, of Amherst, and Thomas A. Hill, who 
has been one of the most over-worked energetic 
enthusiasts in the movement and is dtoing all the 
work of the committee up to the time of the con- 
vention, was made Secretary-Treasurer. 

A proposed constitution and by-laws for adop- 
tion at the convention is being put into shape 
now by Mr. Hill. Daily more clubs are beinj 
added to the list of those sending delegates to 
the convention. 

ALL CLUBS FOR HARMONY. 

The Aero Club of Washington is watching the 
new movement with great interest. Dr. A. F. 
Zahm hopes that the "final outcome will be one 
grand aeronautical organization embracing the 
whole country and enjoying solidarity and har- 
mony of action." 

While the Aero Club of Ohio has renewed its 
affiliation with the A. C. A. for another year, 
the secretary, Mr. J. Blake, states : "We * » * 
hope that some course will be adopted that will 
promote general harmony." 

Wright Injunction Vacated. 

New York, June 15.— Vesterday the U. S. Circuit Court 
of Appeals vacated the temporary ini unction granted 
the Wright Company against the Herring-Curtiss Co. by 
Judge Hazel at Buffalo. 

The history of the action is as follows : 

The Wright Co. moved for a preliminary injunction 
before Judge Hazel. He held the infringement and 
validity of the Wright patent had been proved without 
doubt in the hearing and granted the relief prayed for. 
Judge Hazel, however, was willing to suspend the issu- 
ing of the order, but required the defendants to put up 
a SlO.OOO bond until the appeal, which was inunediately 
taken by Curtiss, was decided. Now the Court of 
Appeals has reversed the Hazel opinion, with costs, 
and a trial of the infringement suit will now be had 
before iudge Hazel, with cross-examination of witnesses. 
The $10,000 bond is cancelled. 

The reversal of opinion in the case is not a criterion of 
the outcome, for no trial on merits has been held. The 
Court of Appeals merely holds that on account of sharp 
conflict of evidence and the number of affidavits sub- 
mitted after the original decision, infringement was not 
so clearly established as to justify a preliminary in- 
junction.

Lamson vs. Wright Suit. 

Paxton, Warrington & Seasongood, of CLn- 
cinnati, representing Becker & Blakeslee, of Los 
Angeles, Cal., have filed papers in a suit against 
The Wright Company^ and Wilbur and Orville 
Wright, in the United States Circuit Court for 
the Southern District of Ohio, Southern Division, at 
Cincinnati, by the filing of a bill of complaint 
against the defendants stated, Charles H. Lamson 
being complainant. 

The bill of complaint prayed for an injunction 
restraining the defendants from making, using or 
selling aeronautical apparatus, such as flying ma- 
chines, embodying the invention for which Let- 
ters Patent of the United States were issued to 
Mr. Lamson, January 22, 1901, No. 666,427. This 
patent, it will be seen, antedates by over two 
years the date of application of the Wright patent 
under which patent the Herring-Curtiss Company 
and Glenn H. Curtiss and Louis Paulhan have 
been sued for infringement. The bill of com- 
plaint filed as above also asked for an accounting 
of damages and profits. 

The Lamson patent, while stating that the in- 
vention relates to "ribbed aerocurved kites," nevei-- 
theless sets forth that the construction is capable 
of use as a flying machine by the application of 
suitable propelling and guiding mechanism. The 
patent discloses means for "tilting or inclining" 
the tips of the wings or planes at each side of the 
body, and these means are claimed to be equiva- 
lent to those embodied in the Wright patent and in 
the Wright flying machines. 

The patent contains the following claim : 

"The herein-described kite having a 
central frame, wings projecting out 
from each side of said frame and 
means for tilting the tips of said 
wings with relation to the body of 
the wing." 

Mr. Lamson charges that the Wrights simply 
incorporated in their flying machine his inven- 
tion; directed at maintaining lateral stability by 
warping or twisting the wings or supporting sur- 
faces. 

Becker and Blakeslee say : "We 
understand the Wrights insist that 
anybody can use a box kite, but 
Lamson's kite as shown in his patent 
is a triplane comprising ribbed aero- 
curves and connecting posts or up- 
right standards jointed thereto corre- 
sponding to Wright construction. Also 
tip warping or tilting means and a 
tail or rudder having horizontal and 
vertical members. Lamson's device 
as patented and operated resembles 
closely general flying machine struc- 
tures minus propelling and guiding 
mechanism." 

Judge Hand, in his opinion in the Wright-Paul- 
han case, said : "I cannot see any relevancy in, this 
patent." 

The larger illustration gives a perspective view 
of the Lamson kite with the covering removed 
from the upper wing on one side. The tilting is 
effected as follows : 

"A general adjustment is made by 
guys "K," each of which is secured 
at the front lower comer of the frame 
'.\' and at the under side of the 
upper arm 'C by screw-eyes, or by 
other suitable means. By adjusting

the positioa of these screw-eyes a 
general adjustment of the wings on 
each side may be made. A more deli- 
cate adjustment is obtained * * * 
by loosening one of the diagonal tie- 
wires of the panel and' tightening 
the other. The simple means here 
shown for accomplishing this result 
are two loops f, adapted to slide on 
the uprights d, each of the two 
diagonal tie-wires passing through 
one of these loops. By sliding both 
of these loops up or down, the inclina- 
tion of the ribs to the horizontal is 
adjusted with great precision."

♦♦•M-************************** 



I'aris. June lU. liJKt. 

The immediate ueiKlilioi'liood of I'aris has lieeii 
very (juiet for the last few weeks, so far as 
aviation is concerned. This is due to the un- 
seasonable weather, which during almost the whole 
of that time has lieen, either windy or rainy, or 
both windy and rainy. Two or three hail storms 
liave been thrown in for good' m<?asure. 

A week ago, however, M. Bleriot, at the suburli 
of Issy-les-Moulineaux. flew on his monoplane be 
fore the Chinese Prince Tsai Tao with, I under- 
stand, profitable commercial results. Another at- 
tempt by a less practiced hand on, May 14th was 
less successful, the aeroplane being upset by a 
gust, with some damage to the apparatus. 

On May 19th, the weather again permitted 
flights at Issy just at sunset, and 1 watched 
two Bleriots and a Sommer biplane manoeuvre 
at will above the wide parade ground. Cap- 
tain Maurice Clement also flew very steadily in 
the large Clement-Bayard biplane driven by a 
4-cylin.der 40 h. p. Clement motor fitted with a 
clutch and gear between the motor and the pro- 
peller. Capt. Clement preferred to make his turns 
while running along the ground, and stuck to low, 
straightaway flights. His biplane is controlled by 
means of auxiliary stal)iiizers of the Ilerring- 
Curtiss type. 

A Swiss aviator, M. Audemars. was out with his 
Santos-Dumont Demoisi-lle. This monoplane trav- 
eled very fast, but its pilot also habitually flew 
low and made his turns almost entirely on the 
ground. A Voisin cellular biplane was exercised 
up and down the fleld, but I did' not see it leave 
the ground completely at any timie. It seemed 
to be tiuite unstable laterally, even in the compar- 
atively calm weather which prevailed. There were 
in addition two experimental monoplanes, one a 
Vendome, which also ran briskly across and around 
the fleld. But they, too, kept always In touch 
with Mother Earth. The exhibition as a whole 
impressed me with the caution of the French 
aviators while practising. 

The Santos-Dumont Demoiselle is certainly an 
ingeniously designed and compact little flyer for 
lightweight pilots. It is a redtiction of the aero- 
plane to its present day minimum limits, and is 
at the same time an unusually sijeedy machine. 
Some eight or ten of these little monoplanes were 
in the Clement hangar at Issy awaiting their try- 
outs. Among them was the one which I ordered 
last December, jointly with Mr. S. A. Reed of Xew 
York, for experimental flights around Xew York 
City. Before the weather had cleared enough to 
permit a trial, I had decided to change to a 
Bleriot. Ai)parently no one of my weight had ever 
piloted a Demoiselle ( I weigh over 80i kilos ; 
Santos-Dumont is reported to weigh 48 kilos) , and 
the owners of the other machines at Issy were 
mostly in the featherweight class. In spite of 
their light weight, however, minor accidents to the 
apparatus on landing were frequent, and most of 
the machines at Issy had been reinforced at several 
points. In view of these and other considerations 
— the Bleriot, for instance, should l)e easier to 
repair after an accident — it seemed advisable to 
change to the larger and heavier apparatus. 

M. de Lesseps" feat of" crossing the Channel 
aroused some interest, but no very great entliu- 
siasm. "Le Temps" of the next day. in fact, left 
him still in the air, as it recorded his departure 
from French soil Saturday afternoon and had' no 
report of his coming down again, either on this 
or on the other side of the channel, or even in the 
channel itself. Conse(iuently as late as Sunday 
afternoon rumors reported both success and failure. 



I have just returned from an all-day trip on the 
invitation of M. Henri Farman to the aviation 
grounds at Mourmelon, near Rheims. Unfortunate- 
ly M. Farman was not there, but his courteous 
chef d" atelier, M. Fremri, showed me through the 
works. The shops are largely of temporary 
wooden construction, one story high. They are 
building two types of Farman biplane, both of 
which carry the high grade Gnome rotating motor. 
The lighter model has the lower plane some twelve 
feet shorter than the upper plane, the upper plane 
in both models being about 3.5 feet long. The 
special cloth used is given a smooth waterproof 
coating after attachment. The cloth is not mounted 
OIL tile bias, but has the threads parallel to the 
main dimensions of the machine. 

Cnfortunately a sharj) thiniderstorm prevented 
flying most of the time I was at Mourmelon, but 
toward evening it cleared ott' and three or more 
machines took the air. These included a standard 
Farman. an Antoinette, and a new model Voisin. 
witli ailerons of the Ilerrlng-Curtiss type instead 
of the familiar vertical panels. The Voisin Com- 
pany are putting this new style on the market for 
racing purposes. This change marks the liiial 
adoiJtion. Ijy all the prominent French builders, of 
the Wright method of stabilizing. 

The Bleriot. Santos-Dumont, Grade and Tellier 
are direct copies of the Wright patented invention, 
while the new Voisin and Clement biplanes follow 
the Herring-Curtiss modification by using inde- 
I)endent stabilizing planes. The .\ntoinette. Far- 
man and Sommer machines infringe by employing 
hinged flaps or ailerons on the main planes. 

The editor of L'Aerophile expressed his gratiflca- 
tion and interest when I presented the card of 
.VEUo.NAt'Tics. He was naturally familiar with the 
l)Ul)Iication, and much interested in our attempts 
in America to improve on and avoid the Wright 
patents. In France they find it diflicult to under- 
stand the legality or justice of the Wrights' posi- 
tion. It is so obvious to foreigners that the wide- 
spread practice of aviation in the Ignited States 
is smothered by the Wrights that they cannot 
understand the American aciiuiesceuce in what ap- 
pears to them to be unjustifiable tyranny. 

The photographs of the successful Newburyport 
flights of the Burgess "Flying Fish" aroused the 
interest of French constructors and' aviators, as 
this is the first successful model, other than the 
cellular Voisin, which is completely secure against 
infringing the Wright patent. The first Burgess 
production is more accurately termed the "Herring- 
Burge.ss Flying Fish," as Mr. A. M. Herring person- 
ally contributed to the design. This designation, 
however, leads immediately to confusion with the 
better known Herring-Curtiss flyer, which is not 
free from legal difliculties with the Wrights. In 
this connection, a late issue of The Car, Lon- 
don, contains an illustrated description of the 
Burgess biplane in flight under the heading "The 
New Curtiss Biplane." The confusion between the 
two rival machines was jiei-haiis increased by the 
fact that I was piloting Mr. I'.urgess' --Flying Fish" 
when the latter was iihotograplied. Xoedless to 
say. Mr. Glenn II. Curtiss. the famous aviator, and 
I are not identical. 

Speaking of the Wright patent, the Paris edi- 
tion of the y^cH- York Ifcnilil had most interest- 
ing news about the revolt against the agreement 
between the Wright Co. and the Aero Club of 
Anierii-a. The new American .Veronautic Associa- 
liciii lias a wide field of usefulness before it. May 
it fill it wisely. 

.Aeroplanes are being ex)iorted in large numbers, 
many of them going to Russia and Kngland. The 
Farman factory reported that four of their bi- 
planes had been shipi)ed the day before my visit, 
while the output of the Ateliers Bleriot is said 
to be approximately thirty a month. 

Builders are still hunting for the best motor, 
and those which give good satisfaction are diffi- 
cult to secure without a long delay. M. Bleriot 
took mc> over all his well-keijt works and showed 
me monoplanes fitted with the following motors : 
Anzani 3-cyIinder, V shape, 23 h. p., air-cooled ;

Clement 2-cylinder, horizontal, 30 h. p., water- 
cooled : Picker 4-cylinder, vertical, 40 h. p., water- 
cooled ; Gnome, 7 cylinder, rotating, 50 h. p., air- 
cooled. Mr. Bleriot has mounted a Clement 30 
h. p. on my machine, but is ready to provide any 
of the other motors according to the preference of 
his customers. An experimental monoplane, de- 
signed to avoid the Wright patent, was observed 
under construction, but it was not sufficiently far 
advanced to justify description. 

Another French monoplane should reach New 
York before long. This is one of the large and 
high powered Antoinettes which it is said that 
Mr. Harkness is taking in under bond for tempo- 
rary exhibition purposes. 

The death of young Hauvette-Michelin in his 
Antoinette at Lyons seems to have been singularly 
unnecessary. An eye-witness tells me that the 
monoplane was rolling along the ground when 
knocked over the turning stake, and that Hauvette

Many of the French aeroplanes, particularly 
those driven by Gnome motors, carry speed indi- 
cators to show the pilots at all times the speed 
at which the motor is revolving. The indicator 
most generally in use is made by Chauvin. and 
Arnoux. It consists of a minute magneto driven 
by a cord from the motor, the current from the 
magneto being indicated on a meter graduated in 
revolutions per minute, which is mounted where 
it may be most readily seen, by the pilot. 

An accomplished fellow passenger on the Ma-

LOS ANGELES CLUB DEDICATES SHED. 

The Aero Club of California held its annual 
picnic on May 29. This picnic was held at the 
motordrome, where the club now has a hangar, 
capable of housing sixteen machines. Eight ma- 
chines are now on the ground and others building. 

Some eighty persons were in attendance and the 
aflfair was in every way a success. The Cannon 
brothers towed their big biplane behind an auto- 
mobile and succeeded in leaving the ground and 
gliding some distance. 

Mr. J. Wood Porter tried out his monoplane 
gliding machine, towed by an automobile, and 
mounted by Edgar S. Smith. The plane is circular 
in shape. The chassis is suspended' from a central 
rectangle, the semi-circular wings being hinged onto 
this rectangle in such a manner as to allow of 
movement in a vertical plane like the wings of a 
bird. The whole surface is also hinged so as to 
allow the angle of incidence to be changed. The 
surface comprises some two hundred square feet. 
After running on the ground for some distance, the 
machine lifted slightly on one side, toppled over 
and became a wreck. 

Three of the machines now at the hangar have 
engines and they will be tried out in the near 
future. 

The Aero Club of California offered a cup to 
the boy making the best showing with aeroplane 
kites. The following boys of the Boys' Aero Club 
contested : Harold Scott, Carl Dorsey and John 
Casey with Farman models, and Edwin Gettings 
with a tetrahedral kite that he called a bimoplane. 
Mr. Gettings won the cup with a seventy-foot glide. 

The hangar was dedicated by Frank C. Garbutt. 
Addresses were delivered by President H. LaV. 
Twining, Charles E. Rilliet, W. H. Leonard, Buel 
H. Green, William Stevens, li. 1. Blakeslee. 

The Pacific Aero Club held its second annual

The Aero Club of Jacksonville now numbers 
more than sixty members. Charles K. Hamil- 
ton was recently the guest of the club at a 
water party. The genial treasurer, W. M. 
Stimson, kindly placed liis handsome motor 
yacht at the disposal of the club, and after 
a pleasant trip down tlie St. John River, witli 
plenty of good things provided, Hamilton was 
made the first honorary member. 

The Curtiss Amateur Aviation Club has been 
formed in Los Angeles, with officers as follows:

A LETTER TO DICK FERRIS. 

San Francisco, Cal., June 1, 1010. 
Editor Aeroxaittics. 
Dear Sir : 

In a letter from Mr. Dick Ferris, published in 
your June issue there are certain remarks that I 
take exception to, and beg that you will publish 
this letter. 

As your representative at the Los Angeles 
Meet it would have been decidedly unethical and 
improper to have taken sides in any local dif- 
ferences or controversies, and if you will re-read 
my report (Marcli issue) you will see that tliis 
was not done, that it was unbiased, in no way 
misleading or derogatory, nor did it ignort> Mr. 
Ferris, as he claims. Though he sliould liave been 
given a great deal more credit for his executive 
ability in handli.ng the meet. This was such a 
widely known fact that I, unfortunately, did not 
enlarge upon it further than to state that Mr. 
Ferris was one of the conceiv.ers, and acted as 
manager. 

As far as "petty jealousies" go, this charge is 
absolutely and obviously ridiculous, as I reside 
in San Francisco, am a vice president of the I'a- 
cific Aero Club, have been actively interested in 
and liave written on tlie sub.iect of aeronautics for 
a number of years, and our fields of activity in 
no way conflict. 

Regretting that the fairness and impartiality, 
wliicii I believe has always characterized my re- 
ports, has been questioned, and assuring both you 
and Mr. Ferris that no injustice was intended, or 
done, I ai>i 

Yours very sincerely,

MOLLER AFTER GOULD PRIZE. 

Referring to engines of tlie twin type with two 
propellers, for wliich Edwin Oould offers a prize of 
$15,000, we liad tlie pleasure of seeing a new 
construction in a two-cycle, double acting twin 
engine, designed by .T. A. Moller. of Xew Rochelle. 
This engine looks very feasible and ought to All 
the bill for aeronautic inu-poses. It has a special 
cooling device and can be built eitlier air or water- 
cooled. Mr. Moller has been studying aeronautic 
devices a good many years and would like the 
co-operation of some gentleman fur the advance 
of the art. 



r.VRTXER WANTED. 

I liave invented and apjilied for a patent on a 
gasoline motor. It is of very efficient design and 
only weighs L' 14 pounds per horse power. It can 
be manufactured, I believe, cheaper than any 
equally good motor on the market. I need a litt](^ 
financial assistance to market this motor. I would 
like to form a partnersliip with some one wlio will 
put up the little cash required. Would make very 
liberal terms with right party. R. E. LEE. De- 
posit, N. Y. 



NEW r^EVICE FOR CONTROL. 

.John C. Press, of Soutli Norwalk, Conn., has de- 
vised a system of lateral control which he says 
is tlie most ingenious, unique and effective yet 
brought out, and does not infringe on the Wright 
patent. It accomplishes, he .says, the same results 
as the warjiing and tilting devices used at nrcsent 
without changing from tlie horizontal, and nives 
great lift without apjireciably increasing head re- 
sistance, and that, as there is no turaing move- 
ment, the rudder does not require to be operated 
in conjunction with the device. 

Mr. Press is anxious to get in touch with some- 
one to assist liim in establisliing liis claims. 



ANOTHER LETTER TO MR. FBRRIS. 

Los Angeles. June 5, 1910. 
To the Editor of .Veroxaiitics, 

Sir : .Vs to the statements made by Mr, Ferris 
in his letter publislied in the last issue of .Vkko- 
.NATTics. I wish to call attention to the following 
misapprehensions under which Mr. Ferris seems to 
be laboring. The Aero Club of California came 
into existence some seven months before it eve» 
heard of 'Sir. Ferris, and it was not through any 
initiative on the part of ISIr. Ferris that the Aero 
Club was organized. 

This club was organized in May. 1008. and it 
was in full swing in the fall of 190S when Mr. 
Ferris pulled off his balloon race. 

From the time of its organization this club has 
held continuous weekly meetings or semi-weekly 
meetings, and at no time in its history did it 
disintegrate or show any signs of disintegrating. 

It applied for affiliation with the Aero Club of 
.Vmerica six months before the international mid- 
winter meet was heard of. but. owing to the slow- 
ness of procedure, it did not receive the papers 
until the movement for the midwinter meet had 
been thorouglily launched. 

Mr. Ferris" statements also do rank in.lustice to 
the members of tlie committee of the Mercliants" 
and Manufacturers" .\ssociation. of which commit- 
ter he himself was a member. If it had not been 
for the ;Merchants" and Manufacturers" .Vssociation 
the Los Angeles meet would never have taken 
place, and it was the business acumen of this com 
mittee that made the meet such a financial success. 

I do not wish to detract at all from the credit 
due to Mr. F(»rris for the energy displayed by 
him in bringing this meet to a head, as it would 
not have taken place had it not been for him also, 
but I do ob.iect to his misstatements with regard 
to the Aero Club of California and his attempt 
to belittle everybody else connected with the meet, 
and to magnify himself. 

Yours very t ruly. 

IT. LaV. twin inc.

Curtiss Uses Palmer Tires. 

The B. F. Goodrich Company of Akron. Ohio, 
has just received a letter from Mr. Glenn Curtiss, 
written immediately after his recent record-break- 
in.i,' flight along the Hudson fi-om Albany to New 
York City. Speaking of his equipment in that 
Higlit, the Palmer Aeroplane Tires, which are of 
• ioodrich manufacture, he said : "The Palmer 
Tires, with which I equip all of my aeroplanes, 
give the best of satisfaction for the purpose. The 
light weight does not greatly impede the lifting 
power of the machine, and the great resiliency 
enables me to land without shock on the hardest 
ground and to pick up speed quickly in starting. 
I am glad to credit a part of the success of my 
aeroplane to the Palmer Tire." 

Mr. Curtiss used the Palmer tire on the winner 
of the International Aviation Cup, Rhelms, France, 
last autumn, and on the winner of the world's 
record for short distance rising from the ground, 
at the aviation meet, Los Angeles, California, this 
year. 

"The light weight which does not greatly im- 
pede the lifting power of the m^achine, and the 
great resiliency" which allows the plane to land 
without shock, were particularly important in the 
Albany-New York flight, when two landings were 
made on the way for supplies, and yet the distance 
was covered in phenomenal time, and with re- 
markable ease. 



The Sacramento Aerial Co., was incorporated In 
.\pril for .$25,000. They are building two machines 
which will be done about .Tune 10th. A lot has 
lieen leased where a factory will be erected for the 
manufacture of all kinds of aerial craft. It is the 
iiii'ntion of the company to manufacture a motor 
which will have many impi-ovements over anything 
that has been put out so far. 



The Gill-r>osh aeroplane which made its debut 
at the Los Angeles Meet, has made over fifty short 
flights. This was on the Curtiss order, but had a 
lipavy automobile motor. A new model, different 
from anything on the niarket, is nowing being 
made and will be flown at the St. Louis Meet for 
novices. 

Several machines on the Coast have made short 
flights with the Hall-Scott motor, which is com- 
paratively new to the aeroplane world. These 
ari' as follows : Wiseman & Peters, Farman type 
ttiplane, at Santa Rosa. Cal. ; Frank Johnson, Cur- 
tiss machine at San Jose with Harold Hall as 
aviator, and Roy Crosby's Greene biplane with 
Harold Hall, rider.

Aero Motor for $250. 

To All the steadily increasing demand for a light 
weight aeronautical engine, the Detroit Aeroplane 
Co., of Detroit. Mich., has undertaken the rather 
ditfloiilt task to put a new motor on the market 
for the most popular price of .$2.50. 

This company has been incorporated under the 
laws of Michigan for .$20,000, with F. Weinberg 
president, for the purpose of manufacturing aero 
motors and other devices. The firm of Wilcox <S 
Carlson Co., of Detroit, makers of marine engines, 
has been bought out. 

The engine is a two-cylinder of the double op- 
posed type, four cycle, and has a bore of 5 In. 
and a stroke of 5 in., and the speed range Is 
between 700 and 1,500 r. p. m., developing between

twenty and thirty horse power according to speed 
and load. The weight is 98 lbs. Both valves are 
placed in the cylinder head, and all four valves 
are operated by one single cam. in this way elim- 
inating a large number of parts, manufacturing 
cost and trouble. The adv^antage of this arrange- 
ment is largely due to the fact that by timing one 
valve the others are timed at the same time. Both 
valves can be detached with their valve cages by 
loosening only two screws, at the same time giving 
free view of the cylinder inside and the piston. 
The engine being air cooled is especially designed 
for this purpose, inasmuch as valve sections have 
been employed of an enormous area, the exhaust 
valve, for instance, being .'>% in- in diameter. On 
the other hand, the extreme large flanges have 
been arranged in doulile distance as customary 
practice shows. This is done to avoid the recipro- 
cating action of the radiation from one rig to 
another, and has been thoroughly tested out on 
French and German motors. 

By means of the double throw crank shaft, the 
pistons are forced in opposite directions, and as 
a result, a bright stream of air is thrown steadily 
inside the crank case and cylinder by each revolu- 
tion, which helps considerably to bring the tem- 
perature of piston and cylinder walls down. This 
in connection with the arrangement of both 
cylinders opposite from each other, and the wide 
spread of the cylinder heads which are directly ex- 
posed to the cooling air draft of the propeller, 
warrants a most efficient cooling under propeller 
load. 

The lubricating system is splash, and the crank 
case, therefore, is oil tight and from the best alu- 
minum alloy. It contains, besides a lubricant, all 
moving parts of the engine, as crank shaft, timing 
gears, cam. connecting rods and pistons. The hol- 
low double throw crank shaft is perfectly balanced 
and made from 40 to .50 pt. high carbon steel, 
heat treated and mounted against thrust by a 
New Departure ball bearing, which feature enables 
a direct attachment of the propeller. All other 
bearings are made from best white brass, and are 
most liberally dimensioned and replaceable. This 
is the strongest keynote of the motor, which is not 
only as light, but as durable as possible, and dis- 
tinguishes itself from all other light weight en- 
gines, because it does not need the care of any 
expert, but can be handled most successfully by 
amateurs. 

Connecting rods and pistons are being weighed 
thoroughly, and this in connection with the bal- 
anced crank shaft is a most satisfactory running 
system. There are some other points of refinement 
employed in the design, one of which is that all 
the strain of the cylinder and crank case is con- 
verted into compression instead of pulling stress. 

The gasoline tank may be mounted in or above 
height of the engine, as the carburetor is attached 
to motor on its lowest point of the crank case, 
forming with the latter a compact unit. The 
crank case itself is provided with flanges for the 
purpose of fastening to the frame of the aeroplane. 
The design, in connection with the very best 
material used, and the very best workmanship ob- 
tainable, warrants a first class product. This, in 
connection with a large output and in always keep- 
ing a number of ready tested engines in stock, en- 
ables the company to market this motor for only 
$2o0. This price includes the ignition systeni. 
consisting in snaptimer provision being made for 
attachment of magneto. 

Propellers are made and attached to motors 
on special request, and are kept in stock in sizes 
between 5 and 8 ft. diameter and 3 to 7 ft. pitch, 
these propellers being the sizes which the motor is 
able to pull successfully without overheating or 
destructive effect. 

Catalogs are sent on special request. The com- 
pany asserts that the price is so low that even 
the most modest aeroiilane manufacturer can obtain 
a powerful engine at a reasonable price. 



Wittemann Catalog. 

C. & A. Wittemann, Stapleton, Staten Island, 
N. Y., have gotten out quite the finest aeronaut- 
ical catalog yet issued an.vwhere. It contains a

Propeller Tests Well 

A test of a pro'peller, the design of which is 
new, made by the Requa-Gibson Company, was 
made at the Curtiss place in Hammondisport on 
June 4. Hugo C. Gibson had gone to the factory 
of the Elbridge Engine Co.. at Rochester, to make 
tests of the propellers on the Elbridge engines. 
Six propellers were taken, one of which was of 
the new type. Owing to the rush of business, 
there was but one of the large engines available, 
and that had been delivered to Glenn H. Curtiss. 
So the tests had to be made at Ilammondsport. 
The engine was hung in a frame suspended from 
the ceiling, and on a spring balance attached to 
the wall the thrust was read. The 7-ft. diam., 
4-ft. pitch special propeller showed' up '■V.\7 lbs. at 
860 r. p. m., the engine developing at the time 
26 h. p. With the balance of the power of the 
motor to draw on. the new propeller should show 
great speed possibilities and economy in gas con- 
sumption. 

Fred Shneider Busy. 

Three more aeroplanes, combination Farmnn and 
\'oison types, will be delivered by the end of the 
month. One will be equipped with a :^-cy Under,

about the same dimensions as the Curtiss. 



Many Aeroplanes Sold in Washington State. 

The Hamilton Aero Mfg. Co., of Seattle, Wash., 
luixc liuilt and sold six machines, including sev 
eral liii)lanes, and are now building two biplanes 
for the international meet, to be e(iHipi)ed witli 
an Elbridge 4O-60 h. p. motor and a Ke(|ua-(;il>son 
propeller. They alread.v have seven orders for 
"1 >nnionoplanes" andi biplanes. Many orders are 
Mniied away because they cannot make immediate 
delivery. 

The Whitehead Motor. 

The first aeroplane to be fitted with a Whitehead 
motor is that of Chas. W. Miller. Following are 
the details of the motor : 

Tile engine is liighly finislied and has specially 
temi)ered steel cylinders with steel water .iiackets 
weldi'd in place. T'nder h.vdraulie pressure the 
ja<'kets stand a pressure of 600i lbs. to the sq. in, 
Forced circulation is maintained at high speed' by 
a gear pump. 

Th(> engine is of the two-cycle type, with eight 
port exhausts to each cylinder. No carburetors 
are n.«ied. a special Whitehead vaporizer being pro- 
vided for each cylinder. Ignition is Bosch mag- 
ni'to. 

The intake is automatic, and is through a valve 
located in the center of the piston- head. The 
crank case is divided into four compartments, 
which serve as pre-compression chambers, and in 
which the gas is compressed to 20 pounds ])er 
square inch, previous to being adtnittinl into the 
explosion chamber. 

When the exhaust takes place, the relief of the 
liressnre in the explosion chamber en,abl(>s the lower 
pi'essur(> in the crank case to force the valve open, 
admitting the new charge into the explosion cham- 
ber, coincident with the escape of the dead ga.ses 
through th(> exhaust ports. 

On the upward stroke a compression of 0.5 lbs. 
i.«! reached, which is considerabl.y in excess of that 
of any other motor, resulting in increased power. 
The exploding charge is at ."00 lbs. per sq. in. 

The bore is .5 in. and the stroke 5i/^ in., making 
it a low speed, high powered engine.

AERONAUTICS 

The cranks are set at quarter tUrns, making 
vibration almost negligible. Being a two-cycle 
type, the power is increased over a four-cycle' en- 
gine of the same bore and stroke, there being four 
explosions for each revolution of the crank shaft, 
as compared with two explosions in the four-cycle 
tj'pe. 

Thus a four-cylinder, two-cycle engine, such as 
the Whitehead, is theoretically much more flexible 
than' a six-cylind'er, four-cycle automobile engine, 
and is equal in flexibility to an eight-cylinder, four- 
cycle engine. 

The oiling system is both by splash lubrication 
and mechanical oiler. The bearings are five in 
number, of phosphor-bronze. There is also a thrust 
bearing on the crank shaft to prevent the breaking 
of the crank case from the pressure of the pro- 
peller. 

The construction of the cylinders of the White- 
head engine is unusual, as they are bored out of a 
solid billet of chrome nickel steel and subjecii'd 
to numerous temperin^s. 

The steel sheet water jackets are welded in 
place by the oxo-acetyh'ue process, so that there is 
no danger of a l)reak in the water-cooling system. 
There is in the Whitehead engine no packing what- 
ever, and all its working parts are of the utmost 
simplicity. 

The crank case is of aluminum alloy, and the 
cylinder bolts run all the way through the crank 
case, thus giving much more than the usual solid 
ity of construction.

('rail Hope. Ky.. a distance of ."O.'Ji/i miles; dura- 
tion 19 hours 55 minutes, highest altitude, 20,- 
600 ft. 

The trip was undertaken with a view of gaining 
the record duration, altitude and distance, but 
the poor quality of the gas cut down tlie supply 
of sand bags. When the aeronauts landed there 
was but one bag left out of the thirty-three at 
the start. 

From 6:50 p. m., the time of the start, till 9:00 
the next morning. I)ut six bags were used. In 
passing over Illinois, the balloon suddenly droi)ped 
from an altitude of 8.(MMI or 9,000 ft. and six 
bags of sand were used to check this sudden de- 
scent, which was accomplished just as the trail 
rope touched the ground. It was found out after- 
ward that a local rain storm probably created a 
rising column of cold air and caused the drop.

Considerable ballast was expended in attaining 
the great altitude. The aneroid was examined at 
about 2 :00 o'clock, and it registered' liOi.eOO ft. 
Xt this point the aeronauts were gasping for 
breath, and this height was maintained for about 
ten or fifteen minutes. It is supposed the balloon 
went consid<>rabl.v higher. The instrument was 
later examined by the makers and it was found 
that this height was the limit of the capacity 
of the aneroid. 

The gas left only slightly filled the balloon, 
and as it tended to collapse, it had a correspond- 
ing tendency to elongate, hence the pressure upon 
the rope extending from the base of the appendix 
to the basket became great. In fact almost the 
entire weight of the rigging beneath the balloon 
was forced upon this single line, and at length 
it parted. This dropped the basket, elongating 
the balloon so suddenly that the line from the 
ripijing panel to the basket became suddenly taut, 
tore open the ripping panel four or five feet. The 
gas rushed out at terrific speed. The result was 
tlic immediate t'ollapse of the balloon and its 
descent to the ground at 2 :4.5 p. m. ,\t this 
time the 350-ft. trail rope was just touching the 
ground. 

The aeronauts were found' unconscious by farm- 
ers. Forbes was laid in a lot of poisin ivy vines 
and suffered from their poison for some days.

WINS THREE CUPS. 

The pilot, Mr. Stevens, wins for the first time, 
until his record is beaten, three cups: 

"La Patrie Montreal," to the Dilot larding 
nearest the office of "La Patrie," 

"Cortlandt F. Bishop," to the pilot making the 
longest flight in 1910, starting from a point in 
Now England. 

The "North Adams Cup," for the longest dis- 
ance made from North Adams. 

A lower current was encountered which begnn 
to drive the balloon towards the States again, 
and it was thought best to land at Drummonds- 
ville. The trail rope was dropped here and the 
aeronaut called out to a farmer to catch it, but 
the man's wife held him back. By this time 
the balloon had come up to a forest where It was 
impossible to descend, so the trip had to be con- 
tinued some seven miles further on the return

'"Aeronautics" ' 
New Year.

It is with somewhat more assurance of 
the ultimate than on three previous Julys 
that with this issue "Aeronautics" begins its 
fourth year. 

Aeronautical affairs of late have reached 
a higher plane and the structure of the Art 
is attached more firmly to the industrial 
chassis. 

In the face of the kindly advice of those 
foremost on the subject the magazine was 
started in July, 1907, when a gas balloon 
was a curiosity and the Wright Brothers' 
flights were still alleged myths. 
^\With the good will and ready support of 
t€se somewhat pessimistic friends, and with 
the appreciation of those who found "Aero- 
nautics" of interest and value, without a 
skip the magazine was continued single- 
handed through three not particularly en- 
couraging years. 

It was steep-angle work, you may be sure. 
No t'me or pains has ever been spsred to 
make the paper as reliable, accurate and 
efficient as possible in its heretofore ex- 
ceedingly limited field. The sun often set 
and rose again on a day's work, but the 
heart was in it, and this, perhaps, made the 
labor lighter. 

In launching upon this New Year I want 
to express my sincere appreciation of the 



many kindnesses thrust upon the magazine, 
and may success eventually alight at our 



doorsteps.

Automatic Stability Problem Solved. 

Liiii,aitn(linal and lateral stability form tlio two 
most important problems in the developnifnt of thr 
aeroplane. Stability must eventuall.v be automatic. 

For some .years past Lieutenant .T. W. Dunne 
who was for some time attached to the Balloon 
Factory at Farnborough, England, but has recently 
continued his experiments at Sheppey on his own 
account, has worked at the problem. A biptane 
designed by him, and piloted by Lieut. (Jibbs, actr 
all.v made several flights in Perthshire in thr 
autumn of 190S. Since the beginning of this year 
flights extending in one case to nearly one mile 
have Iteen mad'e in the Isle of Sheppey. The ma 
chine was recently reconstructed, and was brought 
out once again and tried on the afternoon of May 
27, in a fair breeze. Lieut. Dunne, who i)iloted 
the biplane, arose from the ground after a riir 
of some forty yards and, rising to sixty feet, main- 
tained this altitude for some distance, when he let 
go his grasp of all the steering-levers and absolutely 
abandoned the machine to the air. Pursuing Its 
free flight with perfect stability and steadiness, the 
aeroplane covered a distance of .iust on two miles, 
when lyieut. Dunne resumed control of his levers 
in order to clear a high mound, but. being unable 
to do so, came to earth in a ploughed field. The 
entire length of the flight was about two and one- 
half miles. During its free flight the aeroplane 
gradually rose all the while. 

The importance of this achievement need not 
be insisted upon, it simply proves that the problem 
of automatic stability is in a fair way of being 
solved, and as such Its significance transcends that 
of the ma.iority of sensational sporting and exhihi 
tion flights. During the whole of its free uncon- 
trolled flight the aeroplane remained' absolutely 
stal)le. The aeroplane Is a biplane ; the wings pro- 
ject backwards from the central axis of the ma 
chine, and in plan have the shape of a V with 
the apex in the direction of flight ; the wing tip^ 
are actually situated in rear of the center of 
gravity of the machine. Their combined area i 
."i(>(> square feet. The machine carries no tail no 
steering or controlling surfaces of any kind with 
the exception of a flap hinged to the rear ex- 
tremity of each wing for effecting horizontal aiu' 
vertical steering. A 4-cyllnder, 50 H. P. "Green" 
engine drives two propellers revolving at the rear 
of the surfaces. The wings have a positive angle 
of incidence near the centre, the angle gradually 
decreasing towards the tips, where the angle i 
actually negative. The machine weighs 1,700 
pounds, the loait therefore being about three pound' 
|ier si[uare foot.

How Competition Promotes 
^^^^— Progress ■^■^— 

FOR the third time America's first aviation trophy, 
which commemorates Langley's aeroplane, has 
been competed for and perhaps permanently won 

by GLENN H. CURTISS 

in his record-breaking flight down the Hudson Kiver, 
on May "29th. On July 4th, 19()H, he flew a mile in 
a straight line; last year he covered 25 miles over a 
circular course; and now he has flown 741 miles from 
Albany to Poughkeepsie without a stop at a speed 
of over 50 miles an hour- — a long distance flight 
already increased materially by Chas. K. Hamilton 
in his I hour and 50 minute trip from Governor's 
Isi.Axn to PHiLAOELPniA on June ISth. 
C All this shows what progress has been made since 
we offered the Scientific American Trophy. The 
competitions this year which are to be cross-country 
flights — will evidently be very keen; and aviators 
intending to compete should make entry early.

A Timely Word 
About Motjors 



What you want is A Real Aeronautic Motor, light and yet strong, simple, 
and above all reliable. A motor, moreover, that the average mechanic 
can understand and operate. 

What you do not want is a combination motor cycle, or modified auto- 
mobile, engine. Lightness in these is secured only by the sacrifice of strength 
and efficiency; yet either type is unduly heavy. We have tried both and we know. 
Before you invest, it will be worth your while to write us, and 
hear what we have to say. 

At an expense of several years experimenting, and 
many thousands of dollars outlay, we have at last per- 
fected a high grade, water cooled, four cycle, gasoline 
engine for aeronautic work. 
By special method of 
construction, upon which 
we are securing patents, 
these motors are much 
stronger than the ordinary 
makes, and 




at the same 
time very 
much lighter. 
The 45 
horsepower 
engine 
weighs 3 
pounds per 
horsepower, 



and the 90 
horsepower 
only 2 i 
pounds per 
horsepower: 
-about one- 
half the 
weight per 
horsepower 
of any other ade- 
quately water 
cooled engine. The 
weight as also the 
quality of each engine is 
guaranteed. 
These motors are not of freakish 
construction, either in the number 
of cylinders, or in any other respect. 
They are of the regular opposed type, similar to the famous 
Darracq aeronautic engine with which Santos Dumont's 
machines are equipped, conceded by gas engineers to be the 
smoothest running, and nearest vibrationless type. 

A scarcely less important feature is the fact that our motors are silenced (not 
muffled), which feature is secured without loss of power. They are in fact, the 
only silent motors yet devised for aeronautic work. The importance of this 
feature can not be overestimated; and in connection with their strength, lightness, 
and reliability, places these motors in a class by themselves. 

MODEL El: Two Cylinder, 45 Horsepower; Weight, 135 pounds. Price, $700. 
MODEL E-2: Four Cylinder, 90-Horsepower; Weight, 225 pounds. Price, $1,200. 

EXTRA— Bosch Magnetic Ignition: Model E-1, $50; Model E-2, $100. 
TERMS: 40 per cent, cash, with order. Balance Sight Draft against Bill of Lading. 

Write to US and let us send you Illustrations and description of these Wonderful Motors. 

P. S.— Send for particulars and price of our REVERSIBLE AERIAL PROPELLER. Something

A IR currents and the effect of moving 
L.\ bodies in the air have been a source 
of baffling mystery to even some of 
le most scientific minds, and how true this 
, may be determined by a few interesting 
x'periments, easily made by anyone without 
Kpense. 

Most everyone has seen the so-called ball 
ozzle in which a stream of water moving 

ith considerable force is caused to form a 
dIIow cone by means of a loosely mounted 
- free ball directly in the path of the water. 

matter what force the stream of water has

I A New Control I

THE method of aeroplane control illus- 
trated has been designed by James S. 
Stephens, 7321 Bond Ave., Chicago. 
The upper plane or deck of a biplane is 
made to project at each end beyond the lower. 
This in itself is claimed to add to the sta- 
bility of the machine "by presenting a mare 
efficient lifting surface to the air on the side 
tending to dip, and at the same time com- 
pensating for the deficient lifting power of the 
upper plane due to the resistance and disturb- 
ance of the air currents by the lower plane." 



blow. It takes a little practice to accomplish 
this, but it is worth the trouble. 

The most interesting of all is the experiment 
performed with a funnel and candle. If a 
lighted candle is held so that the flame is posi- 
tioned at about the center of the large end of 
the funnel as shown in Fig. 4, not only is it 
impossible to put the flame out when one blows 
through the small end of the funnel, but the 
flame will be dran'ii info the fuuiiel toward 
the mouth, and no heat efifect will be felt at all. 

Now hold the candle and flame in the rela- 
tive position shown in Fig. 5 and the flame 
can be readily extinguished by blowing through 
the small end of the funnel. 

To my mind this experiment clearly illus- 
trates the theory of vortex rings or more 
truly vortex currents or better yet cone cur- 
rents, and I firmly believe that exploration 
in this field will bring forth new ideas and 
new principles will be discovered that will lead 
to the perfection of air devices in general and 
the propeller in particular, because I do not 
think that the real efifect of moving structures 
in or through the air is understood in spite 
of the fact that flying machines are no longer 
a novelty, and I hope that a general discus- 
sion will arise through the presentation of the 
experiments outlined here.

I Can a Man Fly 
I With Wings? 

By- H. La V. Twining 

[Continued front the July Xunthrr] 



»»n»»»»»»»» i » i »»»»»»m»»»» m»im8 



Some experiments performed by myself in 
1895 have a bearing upon this. If a silk 
cloth be hung up and a turkey wing be spread 
open, it can be vibrated in various positions 
in front of the cloth, and the action of the 
wing on the air can be easily demonstrated. 

If this be done the following results are 
obtained : When the front edge of the ex- 
tended wing is presented to the cloth, and the 
wing is vibrated in imitation of the flapping 
wing, the cloth is sucked in all along the front 
of the wing. This shows that the air is 
moving bodily from the front toward the 
wing. If the rear edge of the wing be pre- 
sented, the air is sucked in along the rear edge. 
If the top of the wing be presented, and be 
vibrated to and fro toward it and away from 
it, the cloth is again sucked toward the wing. 
In fact, it clings to the wing as though it were 
glued there. If the bottom of the wing be pre- 
sented the same thing takes place. This shows 
that when the wing is struck toward the cloth, 
the cloth is not driven away, but, on the 
contrary, it rushes to meet it. 

If now the rear tip of the wing be pre- 
sented, the cloth will be blown violently to 
the rear, downward and rearward. This sim- 
ple experiment reveals at once how the wing 
is acting on the air. 

As the wing beats, the air rushes in toward 
it from all directions except one, and here it 
is blown violently away. From this we are 
entitled to draw certain conclusions. The 
wing in beating creates an area of low pres- 
sure, and the air rushes in from all points 
toward this area, except the point where it 
is blown away. Now the more air the wing 
displaces the stronger the air rushes in. 

When we remember that the air produces 
a pressure of 15 lbs. to the square inch, we 
can see the enormous possibilities here. 
Pressure on the wing is produced then in 
proportion to the displacement of the air. 
If the air were all displaced, then the incommg 
air would press against the wing with a force 
of 15 times 144 or 2,160 lbs. per sq. ft. This 
pressure, of course, can not be realized in 
practice, but the possibility for enormous reac- 
tions lie here. The pressure of the incoming 
air is all utilized in giving lift on the under 
side of the wing. When the wing strikes 
down it meets air coming toward it. When it 
strikes up, the upper surface meets the same 
condition. Here is the rock upon which all 
ornithopters built up to the present time have 
split. The up stroke throws them to the 



ground with as much force as the down stroke 
throws them up. 

Evidently this is not the case with the flying 
birds, because they fly, and if their up stroke 
threw them down, this could not happen. 

What then is the peculiar structure of the 
bird machine that prevents this? Aluch specu- 
lation has been indulged in as to the feathers 
opening on the up stroke to let the air through. 

Just a little intelligent observation of an ex- 
tended wing will show how utterly fallacious 
this assumption is. The feathers overlap so 
that they shingle on top from the part near 
the body to the tip. On the under side they 
shingle the other way. In either case, as the 
air strikes the surface, the feathers bind to- 
gether and present a solid surface to the air. 
The direction in which they shingle cannot 
make any difference in this respect. If we 
take up the wing and blow violently on top 
of it, holding the hand on the other side, no 
air will be felt coming through. If we blow 
against the under side the same result is ob- 
tained. Some have argued that the bird turns 
the feathers edgewise by means of muscles 
in the wing, but I have dissected many wings, 
and have looked in vain for any such muscles. 
If we get hold of the tendons of the muscles 
and pull them, we can see what they will 
do. There are no muscles singly or in sets 
that perform any such function that I can dis- 
cover. 

Furthermore, if one observes large birds, 
such as the pelicans, turkey buzzards, sea gulls, 
etc., as they go overhead, one would be able 
to see the blue sky through them if they 
turned on edge. 

In soaring, the turkey buzzard spreads out 
its feathers at the tip of the wing more or 
less like the spreading out of the fingers, 
but this is a disadvantage, rather than an ad- 
vantage as it lets air through from below. 

Then again, birds in flying throw the wing 
open strongly on striking down with it, and 
fold the outer joint considerably upon the 
up stroke. This accomplishes just the opposite 
result from what those who advance the above 
theory are looking for. It closes the feathers 
together in a tighter mass than on the down 
stroke. It, of course, presents less surface 
to the air on the up stroke, but it serves a 
very important purpose as we shall soon see. 

The reason why the up stroke of the wing 
does not throw the bird down lies in the 
peculiar structure of the machine as a whole. 

The fact that the front edge of the wing 
is attached to the shoulder, forward and above 
the center of gravity is a fundamental princi- 
ple in bird flight. Under these conditions the 
up stroke develops a pressure on the upper 
surface of the wing, which rotates the whole 
machine around the front edge of the wing as 
an axis or fulcrum, and thrusts the bird for- 
ward, in the plane of the wing. If the wing 
is pitched upward, then the resultant rnotion 
is forward and upward. If the wing is pitched 
downward, then it will be thrust forward and 
downward. Whether the wing be pitched up- 
ward or downward depends on the will of the 



3y 



AkkONAuTicS

bird. By raising its abdomen or lowering it, 
it can go up or down as it chooses. When it 
wishes to fly down, it contracts a set of mus- 
cles that raises the abdomen relative to the 
plane of the wings. This raising of the cen- 
ter of gravity also brings it farther to the 
front, and as a consequence, the bird pitches 
forward. If it desires to go upward, it lowers 
the rear of the body, thus depressing the cen- 
ter of gravity and drawing it backward. This 
displacement of the center of gravity with 
Inference to the center of pressure controls 
the fore and aft stability of the bird. The 
fact that this center of gravity is below and 
to the rear of the front edge of the wing is of 
vital importance in the maintaining of fore 
and aft stability. The tail is also used in 
maintaining fore and aft stability. 

The center of gravity acting downward ver- 
tically is pitted against the center of pressure 
on the wings acting upward. The center of 
gravity acts over a lever arm with the front 
edge of the wing as a fulcrum, the feathers 
being the lever arm over which the center 
of pressure acts. These two lever arms are 
practically equal, and the weight and center 
of pressure take no mechanical advantage of 
each other. 

Because of this the body of the bird ro- 
tates downward when the wing is struck up. 
and upward when the wing is struck down, 
thus alternately rotating upward and down- 
ward, around the front edge of the wing, 
wedging itself through the air, always moving 
along the line of least resistance, which is in 
the plane of the wing, forward. This can be 
easily seen in large birds like the pelican and 
the sea gull. As the pelican rises from the 
wafer, if one says up, up, etc., as the wing goes 
up, at the same time watching the abdomen, 
one can see plainly that the abdomen goes 
down. If on the other hand one says down, 
down, etc., as the wing beats down, one can 
easily see that the abdomen rises. Further- 
more, by watching the head, one can see that 
it goes down while the abdomen goes up and 
vice versa. 

This can be seen in the pigeon as it is about 
to alight. When the sea gull is coming direct- 
ly toward one, the motion of the head, as it 
bobs up and down, can be easily seen. E. J. 
Marey demonstrated the same thing with his 
tambours, but he misinterpreted the curves 
which he obtained. He interpreted his curve 
to mean that the bird was driven backward 
on the up stroke. Such a result would be 
impossible. A careful perusal of his book, 
and an inspection of his curve will show that 
instead of being driven backward, what hap- 
pened was this : the abdomen was rotated 
downward, on the up stroke, thus giving the 
tambour between the shoulders of the bird 
a backward movement. This registered a 
backward movement but it was not a backward 
movement of the bird, but a backward move- 
ment of the tambour, which was located above 
and on a line with the front edge of the wing. 

The inertia of the weight caused it to press 
on the drum of the tambour, thus recording 



a curve on the kymograph, which he inter- 
preted erroneously. 

The up stroke of the wing thus becomes 
exceedingly effective, and it results largely in 
driving the bird forward, while the down 
stroke develops the lift principally. We can 
now account for the weakness of the elevator 
muscle. When the up stroke is made the 
bird rotates downward, presenting the under 
surface of the wing at a greater angle of 
incidence. The inrushing air striking the un- 
der side of the wing reacts upon it and the 
big pectoral muscle has to take up the strain. 

Thus the elevator merely thrusts the mass 
of the bird forward, while the pectoral muscle 
has to assume the bulk of the work that results 
from that thrust. The folding of the wing 
on the up stroke also helps to produce this 
rotation by giving the feathers at the tip 
greater leverage. 

Inertia plays a most important part, not 
only in the flight of birds but also in the 
flight of aeroplanes of all kinds. When a 
stone is thrown through the air, it does not 
rest on the air, it pursues a path which is the 
resultant of two forces acting on it. 
One of these is gravity pulling it downward, 
and the other is the momentum of the stone 
itself, which tends to keep it in a straight line. 
The resultant curve is a parabola. The saiue 
thing happens to any projectile whether it be 
an aeroplane, a bird or a stone. So by virtue 
of its motion, the bird only needs to strike the 
air often enough to keep up its motion or to 
lift it back through the distance fallen through 
in the interval of time between strokes. 

Furthermore, inertia, whatever its nature, 
acts like a resistance. If a body be moving 
in a straight line it resists any tendency that 
tries to deflect it from a straight line. It takes 
an appreciable amount of time to overcome 
that resistance. Hence, if the moving mass be 
constantly kept in a straight line by reactions 
against the air, its inertia prevents it from 
developing the result of the pull of gravity, and 
b.ence it had practically lost its weight. Con- 
sequently the reactions necessary in keeping it 
in a straight line are those necessary to handle 
its mass only and not its weight. 

Finally a man-carrying machine can be built 
weighing not more than 80 lbs., which with the 
weight of the aviator, 140 lbs., makes in all 
220 ll)s. The question is, has man power 
enough to get 220 lbs. into the air and main- 
tain it there? At first sight the answer to this 
question seems obvious enough, and the answer 
is, no. 

But if we consider that a soldier can put 
75 or 80 lbs. on his back and march all day 
with it, we see that a man has power enough 
to handle his weight and the weight of a ma- 
chine as well. 

Again a man weighing 200 to 220 lbs. can 
handle his weight, altheugh possessing no more 
Dower that a lighter and more sinewy man. 
In order to accomplish this a man must bring 
his whole muscular system into play, in oper- 
ating the wings ; and this must be done also 
to the best mechanical advantage possible.

lERONAUTICS 

This has been done in the ornithopter men- 
oned above. Hand and foot levers have a 
lechanical advantage of 4 to i in their attach- 
lent to the front edge of the wing. The 
perator stands on the foot levers and grasps 
le hand levers. These i\NO sets of levers at- 
,ch to the front edge of the wing on opposing 
des of the main bearing of the wing upon 
le frame, so that the weight of the operator 
thus thrown alternately upon the levers 
the up and down stroke, the weight being in 
ict constantly supported by the opposing pulls 
: the hands and feet, around the bearing 
[ the wing upon the frame. The weight to 
lifted is 220 lbs. This is then to be lifted 
/ striking the air with the wings in an up 
id down stroke, so that only a iio-lb. reac- 
on needs to be developed under each wing in 
-der to lift the machine as a dead lift. The 
^plication of a 30-lb. pull between the hands 
id feet brings a 120-lb. pull to bear on the 
ing in order to depress it. This is 10 lbs. 
ore than necessary in order to balance a 
o-lb. reaction under the wing necessary to 
ft the machine. Under these circumstances 
cperience has shown that the wing can be 
■iven fast enough to develop this reaction. 
1 fact the wings on the above machine will 
Dt have to make more than 60 half beats per 
inute in order to develop this reaction. With 
le wings made a trifle larger, tlie speed can be 
;ry materially reduced. Experiment has al- 
>ady demonstrated that the pressures can be 
anually developed and that with a 30-lb. pull 
1 each side or 60 lbs. in all.

It must be recognized that this pull is the 
maximum pull necessary to get the machine off 
the ground. After getting on the wing no 
such pull will have to be maintained. The 
only remaining thing to be determined is as to 
whether the wing is a very efficient trans- 
former of motion or a very inefficient one. If 
it be very inefficient then man cannot hope to 
fly by manual power, but if it be a very efficient 
one then in my judgment men will fly by the 
exercise of their muscles as a bird does. 

The wing when operated displaces the air 
as before shown, and in so doing creates air 
currents toward it, and these air currents pro- 
duce a pressure upon the wing in proportion 
to the mass of the air displaced, hence there 
is practically no slip; because the greater the 
stream of air driven to the rear, the greater 
the pressure returned to the wing by the in- 
coming air. On this account all the energy ex- 
pended on the air comes back again in the 
shape of pressures which drive the machine 
forward and give it lift. There are frictional 
losses of course. 

In this paper some of the principles only 
are considered. There are others that we 
can hope to attack with some intelligence only 
upon the completion of experiments now in 
progress. Experiments only can furnish the 
data upon which to base the calculations. 

The ornithopter above described is fully 
protected by pending patents.

IF IT be admitted that the engine gives less 
power, it naturally follows that the propeller 
gives less thrust, and the surfaces have less 
lift than they would have with larger power. But 
it would be wrong to assume that the propeller 
gives materially less thrust at the same speed in 
dry air than it does in moist, or that the lifting 
surfaces, at the same speed and inclination, give 
less support in dry air than in moist. On the 
contrary, at a given pressure and temperature the 
density of dry air is slightly greater than the 
density of moist air : it may be as much as 1 per 
cent greater. Now, for a given speed and angle 
of impact, the thrust or support varies directly 
with the density. Hence, at most it could vary 
but 1 per cent due to moisture, all other condi- 
tions being the same.

Height Records Broken 





Indianapolis, June 12-18. 

I'.V 1;. K. SCOTT. 

The Exhibition Department of the Wright Broth- 
m-M Company made its initial bow to the general 
l)iil)lic at the Indianapolis Motor Speedway during 
the weeli of June i:M8. Several important points 
were demonstrated at this meet ; points of interest 
to promoters as well as to aviators. 

So far as the flying itself was concerned:, the 
meet proved pretty conclusively that the Wright 
aeroplane is a very steady and dependable ma- 
chine. There were about sixty flights during the 
six days of the exhiliition. and there was no sug- 
srestion of an accident. 

In the tranquility of the performances — the in- 
variably successful starts, and quiet, uneventful 
landings — lay the chief beauty, from the writer's 
standiioint of the meet. 

But in just that same tranquility lay its chief 
ihawback from the standpoint of the box-office. 
I'eace and quiet are all very well in their way, 
but after a man has loafed around a railroad' sta- 
tion thirty-eight minutes waiting for transporta- 
tion to the field, has quietly sat on a plank up- 
h!)lst('red blcarlier divan at a temperature of 120 
Kahr. for tluci' lioms waiting for something to hap- 
pen, and with equal peace of mind finally watched 
— at a distance of half a mile or more — these 
ureat white liirds rise gently into the air and sail 
Ijlacidly around the track until fancy moved them 
to descend, that man is apt to lean toward some- 
thing more stirring than the prospect of quietly 
walking two or three miles along a country road 
to where he can find a suburban trolley to take 
him back to town. 

Walter Brookins furnished the incidents of most 
spectacular interest during the week. The first 
clay, after several races against himself around 
an unmeasured course, Brookins made an attempt 
at an altitude record. His altitude was taken by 
A. B. Lambert, of St. Louis, with a combination 
of yard-stick and two pin-points an inch apart. 
.\ttached to the aeroplane was also an instrument 
for recording altitude. This was hung between 
the planes on, a strap, but is said to have been 
put out of commission by striking guy wires as 
it swung about. 

NEW WORLD RECORD. 

Brookins climbed' for twenty-four minutes, at 
which time Mr. Lambert announced the altitude 
of the machine as 4,884 ft., as against Paulhan's 
Los Angeles record of 4,165 ft. The descent lasted 
about six minutes. 

Brookins, in an earlier attempt, had ascended 
2,093 ft. It was the greatest altitude attained by 
a novice and the greatest ever made in an Amer- 
ican-constructed aeroplane. 

Brookin's flights were a revelation. lie cut 
sliarj) circles, mounted quickly as a bird, shot to 
the ground, swooped and dived, liringing out en- 
thusiastic applause. 

Twice during the day Orville Wright flew, on 
one occasion taking up Carl G. Fisher, of the 
I'rest-O-Lite Co. 

IP 2,083 FEET. 

The altitude record was again assaulted on 
Tuesday, .Tune 14. Brookins climbed for 12 min- 
utes. The engineiM's who took the altitude by 
triangulation. figured his altitude at 2,083 ft., 
and these figures were corroborated by the record- 
ing instrument which on this occasion was prop- 
erlv fastened. The descent lasted six minutes.

Sensational Flying % 

4* 

A featiu'L' of the second day was a "contest" 
lift ween a Wright aeroplane and an Overland 
40 h. p. automobile risked as a "wind wagon." 
A stock car was stripped and driven by a wooden 
propeller 8 ft. long, at 750 r. p. m. Official figures 
arc lacking but the Overland companv states that 
5 miles were made in 5:20 (5;i miles an hour), 
while a figure gleaned from another source gives 
the time at 4:58 for 'IVo, miles. The car weighed 
1.800 pounds. The drive shaft was not connected 
with the differential. The propeller was driven by 
a chain from a driving sprocket having 17 teeth 
attached to the shaft, the chain running over an 
overhead shaft with a sprocket of .'U teeth. 

Johnstone made his long>^st iiight, 55 minutes, 
on this day. going up to 920 ft. altitude. 

Orville Wright flew again on the 15th making 
beautiful maneouvres in the dusk, after the pro- 
gram had been delayed by rain. 

BIlOOKI.Ns' M.4RVELL0US TURN. 

Perhaps the most sensational event of a thrilling 
week was Brookins' quick turn on June 16. Ho 
made a complete circle in 6 2/5 seconds, and his 
main i)lanes assumed so nearly a vertical position 
that many thou-jht he was falling. Only one of 
the many photographers on the field had enough 
presence of mind to snap a camera at him. This 
one picture was caught when the machine had 
begun to take its normal position, but the angle 
with the ground is still a very sharp one. This 
is reproduced in this issue. 

3,876 FEET HIGH. 

Arch Hoxsie's motor stopped while Ralph John- 
stone was making a 44-minute flight and ho had 
to land outside the Speedway. Then Brookins 
went up for anothiT altitude flight and after climb- 
ing 45 minutes, reached an altitude of .3,876 ft., 
officially measured liy city surveyors. The flight 
lasting 54 minutes 20 seconds. The barometer 
carried on the machine registered but .".700 ft. 




.\NOTHEI! NEW RECORD. 

Again on Friday. June 17, Brookins made 
another try for the record. He carried two in- 
struments — a barometer within plain sight and 
the recording instrument — and his altitude also 
was taken by reputable engineers. Brookins 
climbed steadily for 55 minutes, and his barome- 
ter showed liim: to be about a mile high. The 
engineers had no opportunity to catch him at 
his greatest height because he was then so far 
from the earth that he could not exactly locate 
the Speedway and consequently sailed, still climb- 
ing, twice across the course out of range. The 
duration of the flight was 1 :04 :00. 

-Vs if the climb in itself wore not suflicientlv 
sensational, Brookins" motor stooped at an esti- 
mated height of .3.000 ft. He then was perhaps 
four miles from the center of the Speedway, and 
the spectators, not realizing that the engine was 
no longer running, wondered whv he was making 
the long descent in almost a straight line. The 
aer(.i)lane just made one long streak'for the eai'th, 
and landed beyond a clump of trees at some dis- 
t:nice from the track. There was a rush of ex- 
liii'd newspaper correspondents and spectators 
tnwnrds the automobiles, but it was stopped when 
sdiiic one with a field glass announced that the 
landing was safely accomplished. The altitude wa^ 
'illicially measured as .XiiuILJt-. a "cw world's 
record. During this flightjHTin stone and Hoxsie 
each were flving.

Numerous good flightf? were made during the 
week by Hoxsey. Johnstone, La Chappdle and 
Cotfyn, but they were uneventful because of the 
lack of competitive features. A number of races 
were scheduled but none were actually attempted. 
Ten flights with passengers were made. 

To Captain G. L. Bumbaugh belongs the credit 
of making the flrst flight on the Indianapolis 
Speedway. On Friday, preceeding the opening 
of the big meet, and while the Wright forces 
were engaged In assembling their machines, the en- 
gine for Captain, G. L. Bumbaugh"s machine was 
delivered on the grounds. Carl A. G. Fisher, 
owner of the machine, offered to wager Roy Knab- 
enshue, of the Wright Co.. that Captain Bumbaugh 
would be in the air before any of the other 
■planes were ready. The wager was accepted and 
both sides hustled to get their machines in readi- 
ness. Captain Bumbaugh's engine, an Elbridge 
"Featherweight" 40-CU h. p., was hastily installed 
and the aeroplane brought out of the tent. At 
the flrst attempt Captain Bumbaugh's machine 
rose from the ground, after a run of about 100 
yards. But the Captain underestimaied his power 
"reserve and the machine shot into the air about 
.30 ft. before he thought to reverse the elevating 
plane. When this was done his descent was as 
rapid as his rise had been. Skimming the ground 
Captain Bumbaugh again rose and' on this attempt 
flew for about half a mile before the tricky eleva- 
tor plane again lirought him to the earth. 

Such repairs as were made necessary by this 
rapid desctjnt were completed by Monday, the flrst 
day of the meet, and early in the evening Captain 
Buml)augh prepared for another try. This time he 
was over cautious in the other direction. Realiz- 
ing tliat the povverf\il engine might drive him into 
the air faster than he cared to go, he deflected 
the elevator planes befor the start. The machine 
got away with a rush. A slight obstruction was 
'on<-ounte'red. just enough to jolt th(> machine clear 
(if the ground ; with the deflected plane in front 
and the thrust of 511 h. p. l)ehind. the aeroplane 
keeled over onto its head, burying the aviator in 
the ruins. The engine continued running, the pro- 
pellor threshing the guy wires, until Captain Bum- 
baugh recovered sufficient presence of mind to 
kick loose his ground wire. To the immense relief 
of the spectators Captain Bumbaugh a minute 
biter rose to his feet and waved a reassuring hand. 
The damages to aviator and machine looked serious 
but fortunately were of fueh nature as to be, easily 
repaired. 

Several short flights were attemi)ted during the 
weeks l)y .7. W. Curzon, but his big Vivinus motor 
did not' deliver power enough to offset its own 
weight and carry the machine into the air. Mr. 
Curzon announced his intention of replacing it 
with an Elbridge "Featherweight." 

Lincoln Beachey had his monoplane, and there 
was the Marquette and the Shaw biplanes but 
none of these flew.

Atlantic City, N. J,, July 4. 

BY n. r. TATTER.SOX. 

The series of exhibition flights organized by the 
Atlantic City Aero Cluli, composed of the hotel 
and business men of the town, costing .$25,000, 
was a great suec.ss A sjction of the beach wis 
si>t apart for the use of the aeroplanes, and every- 
thing was free to the public. The flights were 
sanctioned by the National Council, represented by 
Augustus Post and Henry M. Neely. 

On July 4 Curtlss made his flrst flight on the 
beach between two piers in a stiff breeze. The 
enormous crowd made flying dangerous. 

The next day Curtiss made three flights, the 
longest being 8 minutes. This was made over 
the long piers, up and down the beach at a height 
of about 2(>0 ft. and out over the sea. 

On the Gth it was necessary to run close to the 
water to get hard sand. The tip of the propeller 
was caught by the Incoming waves and broken 
at the ends. With another propeller a flight of 
15 minutes was made, circling over the piers and 
the boats anchored near the shore. Then a short 
flight. 

No flights on the 7th. 

On July 8 Curtiss made a 10 1/2 minute flight 
at a height of 500 ft. Then Brookins got off with 
a 400-ft. flight, cutting various capers and making 
a sharp circle siniibir to the one at Indianapolis. 
This flight lasted about '.)V, minutes. While he 
was in tlie air Curtiss started again and flew above 
him, for 51/. minutes. Starting again, inside 
of 6 minutes Curtiss was lost to view, having gone 
down to Hugh L. Willoughby's grounds, some 
four miles away. T,.anding there he waited for his 
men to come and start him back. Rumors of all 
kinds circulated, as he was gone 1 hour 10 minutes. 

BROOKINS M.\KE.S SH.\RP SPH!,U>, 

A few minutes after Curtiss got away, Brookins 
started and went to a height of 1,80() ft,, making 
beautiful curves and evolutions all the way up. 
lie was up some 15 minutes, coining down in a 
spiral to a height of about .300 ft,, the diameter 
of the spirals being not more than 2()0 yards. 
This was very spectacular. After waiting a 
half hour for Curtiss, Brookins started oft' again 
on a (i-minute "every day flight." Curtiss caused 
.great excitement, as all thought he or his ma- 
chine was damaged. There was cheering when 
someone said "Here he comes." and a speck could 
be seen about 4 miles away. 5(i0 ft. up. 

On July 9 Curtiss took the air flrst and Brookins 
followed "in a preliminary flight. Brookins going 
to aliout son ft. back and forth across the piers. 
These flights lasted and 3 minutes, respectively. 
A half "hour later Curtiss started on a 54^- 
minute flight for a moving picture man. Again 
Curtiss started, before Brookins was ready for 
his altitude flight, but flew only from one pier 
to the other. On Sunday Curtiss made one flight 
of 4% minutes. 

BROOKIX.S M.\KES .WOTHER WORLD RECORD. 

Shortly after this landing Brookins started on 
his wonderful altitude flight. In 53 minutes lie 
had reached a height of 0,175 ft., the highest 
yet attained by aero|)lane. The previous official 
altitude flight " is also held by Brookins, being 
4,030 ft. The latest forei.gn record. 4.(>15 ft., was 
made recentlv bv I>atham in France. This day's 
flight exceeds all attcnpts by 1.2:!fi ft. His de- 
scent, without power, f >'■ lai k of ga'^oiine. took 10 
minutes, having been in the air 1 hour .? minutes. 
.Vfter landing he joyfully rushed to telephone 
through cheering crowds to 'phone the news of 
his success. This rec( rd won for him the .i;5.(M)0 
ofl'ered as a height prize. 

While he was making this llight. Curtiss started 
again and made short fliglUs of two or three 
miles, circling between the oiers several times 
before landing for the last time during this day 
of exhibition work. 

On Sunday. July 10. Curtiss gave an exhibition of 
a flight in a" wind estimated by himself and others 
to be 20 miles. But for the enormous crowd, 
estimated at l()0.0n.O, along the lioard walk, piers 
and housetops. Curtiss would not have attempted 
the flight owing to strong wind and high sea 
rolling. He received great cheering for his 5- 
minute flight, circling between piers and over the

ocean. Curtiss reached a height of about 300 
ft. during flight. The Wrights will not fly. or 
allow their own machines to be flown on Sunday 
so Brookins did not fly this day. ' 

CURTISS FLIES 50 MILES. 

.Tilly 11. Curtiss started flying for the .$5,000 
.-.(I mile prize at .S :24 o'clock. .Vfter flnishing 50 
miles;, or ten 5-mile laps around piers, he circled 
.Ulautic City. Entire flight lasted 1 hour 21 
minutes. The average height was 700 ft. During 
the flight finite a southwesterly breeze was blow- 
iii^;. making a record speed flight impossible. 
The actual time for the 50 mies was 1:1 j:00. Tlie fastest 
lap was (irOI 4-5, a speed of 49. ss miles per hour. Tlie t ime 
made was not as sood as previous records iield by Cur- 
tiss machines. This won for liim S;,5,000, as the Wright 
machine did not try for it. 

Brookins made the ne.xt flight and for 15 min- 
ites gave a fine exhibition of the control he has 
if the Wright machine, twisting and turning at 
ilmost impossible angles. 

Curtiss then flew from the Million Dollar Pier 

Old Pier to get ready for his record-climbing 
light. Before this was started. Brookins attempt- 
(1 flying with Mr. Cofl'yu, another Wright pupil. 
s passenger. At 6 o'clock the machine ran down 
be monorail, but failed to rise. It was pushed 
■aek to starting point and another trial took the 
iiaehine up to an altitude of 300 ft. at times. 

1 very fine flight was made for 15 minutes with 
hort turns and dips. After the descent, Curtiss 
\:\(]i' the most notable flight of the day — the 
iiiekest time for reaching l.OOd ft. lie actually 
'ached between 1,500 and 1,000 ft. in the re- 
iirkable time of 5 minutes .5? .seconds, traveling 
I .1 straight line for about two miles, turning 
len and descending to earth. Shortlv after land- 
ng he flew back to the Million Dollar Pier, carry- 
is [.ineoln Beachoy as passenger. Wliile hauling 
lie Curtiss machine up the platform to house 
t. v. Coffyn made a short exhibition flight in the 
bright machine used by Mr. Brookins. This la.sted 

minutes, reaching about 150 ft. at times. This 
M<Ir(i the last intended day of the aviation meet 
I Atlantic City — l)ut the aviators had been pur- 
laded to remain over another day. 

BROOKINS' MACHINE ST.\XDS ON END. 

July 12. At .S :.30 P. M.. Brookins started for a 
ight and rose to a height of from !)00 to 1.000 
. and remained in the air some 2U minutes doing 
Imost the impossible at times in his turns. At 
ne turn his machine stood close to an angle of 
7 degrees, and it appeared that he had turned 
>o far by mistake. .Ml held their breath and 
Ohs" were heard ail through the crowd. 



An hour later Curtiss went up to bombard a 
lite-boat with oranges from a height of 400 ft. 
Out of six oranges three would have hit a battle- 
ship, the last bomb landing within 12 ft. of the 
boat. He circled around between piers till his 
orange bombs were exhausted, then landed. Five 
minutes later he was in the air again flving down 
to Old Pier to interview Mr. Shackleford. After 
a half hour's wait the crowd saw him in the air 
again firing bombs at the reporters and photog- 
raphers. This caused great laughter among rhe 
audience to see them dodge from being struck by a 
flying orange which was merely a juicy spot after 
striking the ground or water. This flight ended 
his last exhibition at the Atlantic City meet, 
ihe machine was housed and "knocking-down" 
began. 

Brookins. however, made one more flight doing 
his usual quick turns, and fooled all by coming 
down to earth as if to land and then shooting 
out to sea again, as if he had forgotten some- 
thing, which eventually proved to be true for 
he shot up to .300 ft. and then came down close 
to water. 25 ft. from shore, bringing the machine 
so low that the skids seemed to rest on two waves 
and followed them to shore. Eventually he actu- 
ally struck the water near shore, rising again 
and then landing at his camp. 

It is a strange fact, but during the entire week 
there was not a single accident of anv kind 
except the first day, when Curtiss landed "in deep 
sand and ran into a hole, breaking one post. 
Outside of that not a wire, nut or any part of the 
machines had to be altered from the ft st.day of 
"setting up." 

The weather proved ideal, except one day. and 
the crowds were enormous. The largest day At- 
lantic City ever had was .July 4, when, 'it is 
claimed. 300.000 attended. The entire meet was a 
success in every way. thanks to the manage- 
ment and the whole-hearted way in which it was 
carried out — free to all. 

Montreal, June 28-July 5. 

RY H. K. HITCHCOCK. 

The •■meet" was from one viewpoint, the scien- 
tific, eminently successful, and as a direct result 
an impetus to the interest in and study of aero- 
nautics has been stRrted in this great country. 
Financially the meet was a failure, the expenses 
running to some .$40,000. but the flying was 
good — continuous every day of the meeting, all 
done by the Wright and Bleriot machines. .T. A. 
D. McCurdy only got up once in the early morn- 
ing and quite wrecked their Baddeck TI in land- 
ing with the wind. MeCurdy was unfortun.ate

the whole week. He had trouble getting his 
machine on the grounds to begin with, and as.sem- 
bling was delayed by reason of no shelter. G. G. 
Hubbard, of Boston, was induced to come at a 
late date with his monoplane. built by the 
Canadian Aerodrome Co. of Baddeck. without an 
engine, which had to be sent for to Baddeck and 
it did not arrive until the last of the week. 

The Wright team. Brookins. La Chappelle. John- 
stone and Coflvn. all flew well. Count de Lesseps 
was a striking feature with his two Blerlots. a 
50 h. p. Gnome engined type XII and the smaller 
XI with the Anzani 30 h. p. motor. His 30- 
mile trip to and over the city of Montreal in 
49 minutes was the great event of the exhibition. 
He used the big "Scarabee" with air bags, the same 
equipment he used in his cross-Channel flight. Fred 
Owen and Cromwell Dixon, with their dirigible 
altracted small attention. Dixon tried a new pro- 
peller on the advice of Knabenshue and increased 
its speed. The airship escaped and burst, on the 
fourth dav of the meet. This made quite a stir, 
as the people could not tell whether he was in 
it or not. lie stopped the motor by accident, 
descended, .lumped too soon and missed the guide 
rope. Johnny Mack and one of Ed. Hutchinson's 
men made daily parachute drops from hot-air 
balloons. 

Wm. Carruthers, vice-president of the Interna- 
tional .Vviation A.s.sociation. which promoted the 
meet bousht a Bleriot XI and imported one Milt- 
jen from' France to fly it. Milt.ien's experience 
"at flying was evidently obtained at a correspond- 
ence" school. On his first and only flight the 
machine jumped into the air and then gracefully 
dug its nose in the dirt. Cromwell Dixon, who 
had never been in an aeroplane before, then tried 
it and made a highly sensational and wild flight, 
narrowly escaping accident, but brought it safely 
down. 

SOxMlO OF THE FLIGHTS. 

The feature of the first day was Brookins' 
•> nno-ft. altitude fli<iht. while de Lesseps and 
Johnstone were the other aviators. On the second 
day de Lesseps in a trial for speed lost to La 
Cliappelle, while Brookins made another altitude 
flight of l.r>r)0 ft. On the 2Sth Johnstone was 
up 45 minutes, and Brookins flew to a height of 
1 .•JfiO ft., and was up 20 minutes. The start 
oil the rail was timed, too. at 5V2 seconds till the 
machine was in the air. On June 29 Ralph John- 
■stone flew for 40 minutes and Brookins was up 
21 minutes, flying to a height of 2,450 ft. This 
was after carrying up de Lesseps for a 13-minute 
trip Earlv in the morning McCurdy made a 
flight in tlie "Baddeck II." but. landing outside 
the grounds in the tall grass, the machine was 
partially wrecked. R. Timberlake, who had bought 
a Bleriot XL essayed his first flight. With a 
novice's inexperience, after getting off the ground, 
could not stop in time to save hitting the grand- 
stand. The " next day Johnstone flew for 25 
minutes and Brookins took up Count de Lesseps' 
brother to a height of 1,140 ft. in a flight of 
25V> minutes. Then he made a trip alone up 
2.000 ft. 

8,130 FEET IX .viu. 

On July 1 Brookins again made a high and 
sensational ascent, reaching 3,130 ft. in a flight 
covering 45 minutes. 

DE LESSEPS FLIES OVER CITY. 

The most sensational flight of the meeting was 
de Lessens" .iourney over three bodies of water 
and Mt. Royal in a continuous flight around Mon- 
treal's City Hall and back to the aviation grounds, 
a round trip of 30 miles. The flight lasted 49 
minutes. His face was screened from the oil of 
the Gnome engine by a thin wire gauze mask. 

BROOKINS SETS CANADIAN RECORD. 

On the same day Brookins ascended to 3,510 ft. 
The meet closed on July 5. with small attend- 
ance and few flights. Some of the Wright ma- 
chines were going to Toronto, but two had to 
be rushed away, so these were flown from the 
. aviation grounds to the railroad station, over the 
hills and trees. The landing spot had not been 
investigated and when Brookins and passenger 



flew over they saw they had but a very small place 
to land. Steering sharply down into tall grass. 
the latter caught in the wires and corners, turn- 
ing the machine face down and breaking ihc 
front construction. The second machine they flew 
over made a safe landing. 

Nashville, Tenn., June 21-26. 

I'nquestionably among the most spectacular 
flights that have been made may be numbered 
the two night flights of Charles K. Hamilton dur- , 
ing his exliibitions at the Military Tournament 
at Camp Dickinson. ' 

FLIES WITH SEARCHLIGHT. 

The first flight was in the dark of the early even- 
ing, with the moon obscured by clouds. Hamilton 
flew over the electric light studded grounds, almost 
touching the string of bulbs, then shooting up 
into the air and gliding down. Someone suggested 
a searchlight and immediately there was hustling 
to attach a Prest-O-Lite tank under the s(vit and 
the headlight on the front framework. About 11 
o'clock in the night he was ready and the sight 
of the big automobile lamp flashing up and down 
through the semi-darkness, the moon having de- 
ciled to show her face, was a thrilling one. .\ftei 
flying about a quarter hour a cylinder head Ulew 
oiit and he was forced to land. 

Louisville, June i8th and 19th. 

On June IS, Curtiss lowered his own record 01 
quick starting to four seconds flat, with thi 
Albany-New York 8-cylinder biplane, starting or 
verv rough and grassy ground. Hamilton did i' 
in 3 4-5 seconds at San Antonio last April. 

On account of a very choppy and high wind 
neither Mr. Curtiss nor "Bud" Mars was able t( 
make any very nice flights until after 5 o'clock 
when above a crowd of nearly 10,OOiOi people. 'Mr 
Curtiss carried a local newspaper man for a shor 
flight. 

A stiff wind until late the next afternoon pre 
vented any circular flights. However, after I 
o'clock Mars, at an altitude of 20 to 40 ft., racei 
against Curtiss around the circular track !(► times 
Curtiss keeping about 200 to 300 ft. a1)ove :Mars 
and at all times was directly over him. 

For quick starting. Curtiss got off the grouiu 
in 87 ft., and Mars, with his 4-cylinder 25 h. p. 
got off in 10(> ft. Both of these distances an 
behind past performances of Curtiss machines. 

The total attendance for the two days was ii 
the neighborhood of 17,000 people. 

The meet closed when Mr. Curtiss carried R. 
Rubel, Jr.. local agent for the Curtiss biplane, foi 
a short flight. 

Minneapolis-St. Paul, June 22-25. fl 

At the Twin Citv meet there were Curtiss, Wil 
lard. Mars. El,\. \Vhipple Hall, Lincoln Beachej 
with his monoplane and two dirigibles. Curtis^ 
flew, of course, his S-cylinder machine. Mars hat 
his 4-cylinder Curtiss and Willard had a ne^\ 
Curtiss with a 4-cylinder engine of somewhat 
greater power, the new engine having slightlj 
larger cylinders. Hall had the old 4-cylinde) 
Curtiss sold to Frank H. Johnson in Los Angeles 
Ely had the machine of Henry Wemme of Portland 
a "4-cylinder Curtiss. Charles J. Strobel furnishei 
one dirigible with (iintner as aeronaut, whik 
Horace B. Wild flew the Yager airship. 

The track was a bad one for aeroplane flight: 
and the attendance small. The track was linec 
on nearly all sides with buildings or trees auc 
there was only one spot on the grounds suitable 
for landins-. Every flight of any length had to U 
made out beyond the grounds and return to land 
ing inside. The dirigibles were up every day. bui 
the first. Hall did not get up. all during the meet 

.MI the aeroplanes, except Beachey's and Hall's 
made short flights the first day. On the second tuf 
two dirigibles and Curtiss were in the air at tht 
same time. Besides the short flights. Curtiss madf

Mars Flies Cross Country. 

At Topeka, Kans., J. C. Mars, the only aviator 
at tlie meeting, as Willard did not go, as planned, 
on June 15 attempted to fly 00 miles cross coun- 
try to Kansas City. A landing liad to be made 
at Grantville after nine miles, breaking a couple 
of ribs. These were repaired and a second start 
was made. After going on for four or five miles 
the engine went wrong and another landing was 
made, at Newman. After an hour's stop he pluck- 
ily wont on for a short distance finally coming 
down at Midland. 

Pittsburg, Kans,, July 2-5. 

BY r.\ri. W. II.MtVEY. 

Arch Hoxsey made fourteen flights during the 
4-day Wright meeting at Pittsburg, Kan. In the 
last flight, which was to close the exhibition, the 
wind was blowing very hard and Iloxsey while 
some ."iOO ft. in the air shut off his motor intend- 
ing to glide to the ground, which he had fre- 
quently done before. On account of the smallness 
of the ground he saw that he was being carried 
in his circles towards the bleacher, which was 
filled with people. Having no motor power to 
direct his course beyond the bleachers it seemed 
to him best to point the nose of the machine di- 
rectly towards the ground in front of the stand. 
This he did with a result that the forward steer- 
ing planes were Ivadly damaged. He fell almost 
vertically about 40 or .JO ft. but he was not at all 
injured. The motor and transmission parts were 
found in good order. 

Iloxsey made good flights each day. On the 
second he made three low flights, circling the 
Held several times and having his machine under 
perfect control at all times. The flrst day he left 
the ground three times when a storm interrupted 
the exhibitions. 

Ou the third he made four flights. The first 
three were spectacular exhibitions. He did the 
"Roller Coaster" flight and turned the figure eight 
several times. He had wonderful control of the 
machine at all times and as a climax to the 
aftcrncKin wurk he made a beautiful ascent of 

1,000 ft. 

On the fourth Hoxsey duplicated his exhibition 
of spectacular fliglits and also gave some of the 
feats tliat aeroplanes are supposed to do in times 
of war. He made some short and fast short coun- 
try flights and in the finish carried a passenger 
three times around the field for a total distance 
of about two miles. 

On the last day Hoxsey made his usual short 
spectacular flights. In the last one of these he 
carried Mayor Hoyt and did some beautiful work. 
Up to that time Hoxsey had not had a single 
misban and every attempt that he had made was 
a success. 

Sioux City, Mo., June 29-July i. 

BY P. isr. m'cabe. 

Due to a wind which riii^^ed from 5 to 18 miles an hour 
the flights given here l)y M:\rsand Ely June 29, 30 and 
iulv 1 were far from successful 

On June 29 Mars attempted to circle the mile 
race track, attaining a height of from 10 ft. to 
40 ft. Meeting adverse air currents he did not 
make the circle, stopping several yards short. 
Ely made a similar attempt but he, too. was com- 
pelled to alight without being successful. Two 
other atteirpts were made to get into the air but 
were failures. 

On June .'lO after G o'clock Mars made another 
attempt and succeeded in getting from 40 ft. to 
.50 ft. high and went with the rapidity of an 
exnress train for a short distance but was com- 
pelled to let down because of the winds. 

On July 1, in the evening after the wind and 
the crowd had departed, Mars made a fairly good 
fliahl ascendin<i- to a lieight estimated between 
100 ft. and 150 ft. He circled the mile cour.se 
2V> times and went at a good speed. Ely made 
one circle of the field the same evening but his 
ensines were not working well and he was com- 
pelled to give up before doing anything of a 
sensational mature. Following Ely. Mars made two 
other flights in one circling the fleld twice and 



concluding his performance with his "Mars glide," 
dropping from a position of about 75 ft. in the 
air to an eagle like sweep and then alighting. 

Ely is flying now for Curtiss, using the machine 
sold Henry Wemme. of Portland. Ore. 

Aurora, Ills., July 2-7. 

BY FK.4NK H. BEVIER. 

A. I.. Welch was the Wright aviator who filled 
the .Vurora date. On the 5th after a 20-minute 
flight he had to land in an oat fleld. The starting 
track was brought and in leaving the I'ail one side 
of the planes hit the oats which had not been cut 
low enough and broke several ribs. On the Tth he 
flew for 55 minutes going up to 512 ft. The wind 
was bad and' Manager F. H. Russell, of the Wright 
Co.. kept the machine over two days in order to 
satisfy the public. 

Monmouth, Ills., July 4. 

Charli's W. Miller, wlio bought a machine from 
C. & A. Wittemann tried for an hour and a half 
to get his machine to fly but failed. 

New Britain, July 2. 

Chas. K. Hamilton made a sensational flight 
over the main street of his home town, New 
Britain, Conn., on July 2, after a discouraging 
day. The flight was most sensational. The 
streets were crowded with people, trolley cars 
and automobiles. Crowds had come in from 
nearby towns and the governor of Connecticut 
with his staff was present. The conflict between 
two factions of the business men marred Hamil- 
ton's efforts. On his first flight he landed in a 
swamp and broke parts of the machine which 
necessitated some hours to repair. Still another 
short flight was made. On the third trial, he 
went through a series of hair-raising feats for 
which he is noted and then sailed on his spec- 
tacular flight over the main street. 

St. Louis, Mo., July 11-16, 

St. Louis. July 10'. The first aeroplane meet- 
ing to be held in this country where entrants have 
been required to pay a fee to compete and in 
which there are no hired airmen to take part, 
will open to-morrow afternoon on the temporary 
a via I ion fleld of the Aero Club of St. Louis at 
Washington Park. 111., and continue for six days. 
Ten machines have been officially entered and it 
is expected that all will be on the starting line at 
.3 :.30 Monday afternoon. 

The coming event, known as the First National 
.Vviation ISIeeting for Novices which was organized 
by the Aero Cluli of St. Louis to promote the 
science and sport of aerdiilaning in America, is also 
unique in the resixM-i that none of the entrants 
has ever made a pul)lic flight for pay or received 
cash aviation prizes of more than .'i;250. The Aero 
Club has announced that no flights will be guar- 
anteed, but as nearly all of the machines are 
built along established scientific lines th(>re is 
little doubt that there will be flying every day that 
weather permits Full details will be given in the 
next issue. 

Thomas. Bergstrom and W. C. Robinson failed 
to arrive and are disqualified. 

The following will compete: H. W. Gill, biplane; 
C. W. Curzon. Farman : J. N. Sparling, monoplane; 
J. N. Sparling, biplane (Shneider make) ; II. A. 
Robinson, monoplane: Charles Kuhno, monoplane; 
W. F. S. Zehler. fore an aft monoplane ; Claude 
Harris, biplane. 

Army News. 

From June 1 to June 7 Lieutenant Foulois 
made five flights at Fort Sam Houston, Texas, in 
gusty winds up to 15 miles per hour, varying in 
length from 5 to 14 minutes. No flights were 
made after June 7, as the Aeronautical Detach- 
ment was sent to Leon Springs to assist in install- 
ing the annunciator buzzer system at that jtlace. 

Captain A. S. Cowan. Signal Corps, now has 
charge of the Aeronautical Division, relieving 
Captain Chandler on June 1, 1010.

Curtiss Drops Bombs from Aeroplane. 

Hammondsport, July 1. — Under the auspices of 
the New York World and in the presence of officers 
of the army and navy, who acted unofficially as 
observers, yesterday. fJlenn II. Curtiss carried out 
some tests with dropping lead missiles with col- 
ored streamers attached at a target representing 
a battleship 500 ft. by 90 ft. 

Then, of 14 record shots, 10 hits were made 
and 4 misses within 50 ft. of the target. Six hits 
were made running at 218, lio2. 246, 260, l."15 and 
i:!'.» ft. respectively. The seventh and eighth, at 
liJT and 191 ft., were misses. Next, at 250 ft., 
hit. At 268 and 312 ft. shots were misses. Dast 
three, at .302, 268 and 260 ft. altitude, were hits. 
These shots were made moving at right angles to 
the greatest length of the target. After these 
tests the officers left. 

At sunset four more shots are reported, with 
three hits and one miss, the latter being from an 
estimated height of 900 ft., the machine traveling 
lengthwise the target. 

To-day no bomb tests were carried out, but 
several circles over the lake were made and a 
landing made in the water. A small hydrocurve 
surface is affixed just forward of the front wheel 
for assistance in keeping the machine on an even 
keel when hitting the water. 

RESULTS OF TESTS. 

Mr. Curti.ss gives it as his opinion that to ac- 
curately drop bombs in actual warfare one man 
would have to be carried for the purpose besides 
the aviator, as it was impossible for him to make 
accurate calculations of angle and speed, and sug- 
gests the proper method is to have some kind of a 
gun to fire the projectiles instead of merely drop- 
ping them. 

Dr. Greene Hits Tree Head On. 

Rochester. .Tune 30. — Rochester can now claim 
to be an aviation city from more points of view 
than that of engine' construction. Dr. Greene, 
who has, in the past, made several successful 
flights at Mineola and New York City, and who 
has recentlv moved to Rochester to open an aero- 
plane factory, made his first flight in Rochester 
to-day. 

The biplane which he used was constructed for 



(i. E. De Long of the KIbridge Engine Co., and 
was equipped with a 4 -cylinder p]lbridgo feather- 
weight engine and a RtMjua (iibson 7-ft. diameter 
by 4-ft. pitch regular propeller. 

After making his thrust test with the machine 
tied, and succeeding in developing considerably 
over 200 lbs. thrust. Dr. (ireene decided that he 
was ready to fly, and the machine was cut loose. 
After running over the meadow for a distance of 
less than 100 ft.. Dr. Greene rose at what seemed 
to be an angle of almost 45 degrees to a height 
of, approximately. 50 ft., and then flew directly 
down the field of the Rochester Aero Club for a 
distance of about one-quarter of a mile. 

Th(> start had. unfortunately, been made from 
a point in the field which was protected from the 
lireeze by a large-sized hedgerow of trees, and the 
doctor did not appreciate" the fact that a consid- 
erable breeze was blowing from his right, so that 
as soon as he reached tlii> end of this hedge his 
machine was thrown to the left a considerable 
distance. When the doctor succeeded in righting 
himself, he discovered that he was headed directly 
for a tall elm tree. Of the two alternatives, drop- 
ping down and going under the tree or attempting 
to fly over it, the doctor chose the latter. It 
seemed for a few seconds as if he were going to 
mak(> good. Init when he was within a few yards 
he discov(H-ed that it was impossible, and the only 
thing left for him to do was then to stop the 
engine and attempt to glide rapidly to the ground 
under the tree. This also proved to be impossible, 
and the machine hit the tree head on. at a height 
of about 30 ft. from tlie ground, breaking the front 
control and knocking the machine, of course, to 
the ground. The rear control was also broken 
when the bipane struck solid earth. It seemed to 
the spectators almost impossible that the doctor 
could be alive and whole, looking at the wreck at 
a distance of 200 or 30O yards; but he imme- 
diately climbed out of the wreck and waved his 
hand in assurance that he was all right. 

The flight, from some points of view, was un- 
satisfactorv, inasmuch as it resulted in smashing 
Mr. De Long's machine. However. Mr. De Long 
was more than pleased, inasmuch as it demon- 
strated that the enuine had considerably more 
power than was actually necessary to fly with this 
tvpe of biplane. In the next flights that Dr. 
(ireene makes in Rochester with this machine, in 
all probability, a 3-cylinder feather-weight engine 
will be used.

Daily Flights at Mineola. 

NOT a day uovv passes, scarcely, without 
flights Ijy eitlun- Harmon, Baldwin, Seymour, 
Kussell. Hamilton and others still experi- 
menting. There are always several hundred 
people on hand to view the scene and on Satur- 
days and Sundays the number runs up into two 
to three thousand. Mineola is 25 miles from 
New York on the Long Island Railroad, and the 
grounds are a mile from the station and still 
further from Garden City. 

Philip W. Wilcox has finished and given one 
trial his Farman-type biplane, fitted with a Rinek 
8-cylinder 50 h. p. motor. Lewis Strang, winner 
of the Briarcliff race, will learn to fly it. 

The grounds have been fenced in by the owfiers 
of the property with a high board fence 2,500 ft. 
long along the road, with wire fences extending 
out across the plains at each. There is another 
inner wire fence, to keep people off the course and 
provide parking space for automobiles. A small 
grandstand has also been erected and an admis- 
sion fee is being charged on Saturdays and Sun- 
days. After the expenses have been met, I if is 
announced by the president of the land cornpany, 
the income will be devoted to prizes for the 
aviators. The use of board fence has been sold 
to White & Wood, of 1777 Broadway, New York, 
for sign painting. 



The next day Harmon and Russell provided the 
entertainment, but there was nothing unusual 
in the flying. 

RUSSELL BEGINS PRACTICE. 

On June 29, George Russell, who had never 
operated a machine before, made his first flight 
in a Curtiss machine, fitted with a Harriman 
engine. The machine had been exhibited by him 
during the spring over a theatrical circuit. ,Vfter 
a few days he sold the engine to P. Brauner to 
install in a Curtiss-type aeroplane sold to a 
customer and then got another of the same make. 
In live days Russell was proficient enough to fly 
a distance of about 5 miles. 

On June 29 Mrs. Harmon was a passenger with 
Clifford B. Harmon on a lOi-minute flight. This 
was the first time a woman has fiown at Mineola 
and the third in this country. 

Mrs. W. K. Vanderbilt, Jr., was a passenger 
with Harmon for a short .lump of a minute on 
June iiO. The motor would not mote, and a skid 
broke in landing. Further flying was given up 
for the day. 

Harmon Sets New U. S. Record. 

On July 1 Clifford B. Harmon made a new dura- 
tion record for the United States, 2 hours 3 min- 
utes, beating Paulhan's record at Los Angeles of 
1 houi- 58 minutes. No oflicial figures were taken. 




After Hitting Tree 



On July H the first admissions were taken in 
and a goodly crowd saw Harmon make a 10- 
minute flight alone and then a short one with a 
passenger. In the first he essayed the diving 
trick and quick rises which brought forth applause. 
William Watson tried out the machine he had 
.iust bought from P. Brauner, with Russell's Har- 
riman engine, and got off the ground — and then 
landed suddenly, smashing up the machine con- 
siderably. 



however, of either duration or distance. The 
Mineola field over which he flew has not as yet 
been equipped with the proper markers. It is 
estimated that the distance covered was 100 
miles. 

HARMON MAKES FIRST CROSS COUNTRY FLIGHT. 

On July 11 Clifford B. Harmon attempted to 
flv from the Mineola aviation field to Greenwich, 
Conn., in competition for the Country Life trophy.

At 5 :49 the Gnome engine was got going after 
much trouble, but the machine did not go a quar- 
ter mile across the flekl before Harmon brought 
it down again. Hamilton, who had returned to 
Mineola from Atlantic City, suggested leaving off 
the pontoons which had been affixed for use in 
case of a forced descent in Long Island Sound. 
This was done and a new start made at 6 :14 :50, 
but he tlew no further than Roslyn, a distance 
of 4 miles, passing over roads and" trees and the 
settlements of East Williston and Albertson Sta- 
tion. 

Stanley Y. Beach was practicing with his 
B]eriot-typ3 machine at Lordship Park, Bridgeport, 
ir tending to try to fly across the Sound to Long 
Islrcd. After several efforts the mactire- startcl 
lot the cliff, but Beach Jumped out just In time 
to save from going over with the machine. The 
machine fell and was wrecked. 

On .July 12 Hamilton saw Russell fly for 20 
minutes and then took Capt. Baldwin's machine, 
after weighting down the front end. and flew it 
for 8 minutes. Russell then went out and flew 
another 20 minutes. 

ISR.\EL LUDLOW BUILDING. 

Israel Ludlow is building a biplane at Mineola 
which he states will not infringe anyone's pat- 
ents. He claims it is a remarkable aeroplane, 
with its new patented applications of controls and 
promises it to be so stable that a man can take 
his hnnds ofl' the lever ; that it is balanced so 
well that it will And its own level and will keep 
a level flight without attention on the part of 
the operator. The machine is expected to be fin- 
ished by the middle of August. 

B. T. Babbitt Hyde is having a shed 70 by 40 
ft. erected by C. O. Conklin for the housing of 
his machine. .John H. Tyson, Jr., has bought 
Oreeley Curtis' Bleriot which he recently im- 
ported, and it is to be flown by Louis Strang. 



On the Aeronautical Society Grounds. 

At the present time there are 13 machines on 
the Aeronautical Society's grounds. Those in 
process of building, of the biplane type, are Miss 
Todd. Messrs. Diefenhach, Talmage," Watson and 
Stevenson, Mersratroyd, and Edick and Edwards : 
of the monoplane type. Messrs. Godley, Walden De 
Kilduchevsky, and Rosenbaum. 

Creditable flights have been made by .Joseph Sey- 
mour and George Russell in their Curiiss machines. 
Russell is using a .'!0 h. p. Harriman engine, and 
speaks favorably of it. 

Messrs. Edick and Edwards have had their Cur- 
tiss type machine out and succeeded in getting it 
oft' the ground several times for good distances. At 
the present time they are changing the angle of 
incidence of the planes and expect to have it in 
the field in the very near future. 

Messrs. Watson and Stevenson have had their 
machine in the field with a "0 h. p. Harriman 
motor. On .Tune 2i; Mr. Watson made an abrupt 
ascent for 20 to ."SO ft. and descended just as 
abruptly, smashing the entire outrigging for the 
elevator control. Mr. Watson was not hurt. 

Frank Van Anden has had his machine out sev- 
eral times in charge of Charles Nyquist. formerly 
with Hamilton. At present Mr. Nynuist is keep- 
ing the machine on the ground until they get it 
thoroughly balanced and he has learned to han- 
dle it. The motor is a Harriman. 

E. II. Skinner, manager of South Beach. Staten 
Island, will soon be another addition to the flyers 
at Mineola. He has a biplane of his own design, 
fitted with an Elbridge "feather-weight" 40-60 en- 
gine, with which he has been making short flights 
for several weeks past in the vicinity of South 
Beach. 

The Aeronautical Society is building a shelter 
along one side of its l.*?8-f't. shed. ."^O ft. in width 
to accommodate the machines which are without 
protection except such as tents afl'ord.

National Council of the Aero Club of 
America Formed. 

The "National Council of the Aoro Club of 
America'' was formed at tlie rooms of the Aero 
Club of America on June 23, following the break- 
up, through a shrewd political move on the part 
of the Aero Club of America, of the intended 
.ioint convention of the two organizations, the 
American Aeronautical Association and the Aero- 
nautic Federation of America. 

Twenty-six clubs compose tlie council. These 
are as follows : Aero Club of America, California, 
Kansas City, Kansas State. Dayton Aeroplane, 
Philadelphia (now extinct). .Sar.-ifosra Springs, Illi- 
nois. Minneapolis, Utah. Spiiiigficld, Inti'rc()llegiate, 
Harvard, Baltimore, Washington. Atlantic City, 
Dayton Aero Club, Pittslield, New England, Canton, 
Pasadena, Pennsylvania, Aeronautique of Chicago, 
South Bend, Buffalo and Milwaukee. 

An executive committee and officers were elected 
to serve until the second Tuesday in December, 
when a convention will be called in New York. 

The executive committee and officers are as 
follows : 

Clifford B. Harmon (A. C. of America), chair- 
man; W. B. Strang (A. C. of Kansas City). 
A. B. Lambert (A. C. of St. Louis), Dr. J. C. Eber- 
hardt (Dayton Aeroplane Club), Dr. Albert F. 
Zahm (A. C. of Washington); .Vice-Chairmen — 
Oeorge'M. Myers (A. C. of Kansas City), Chas. J. 
(Jlidden (A. C. of New England). .Tames E. Plew 
iX. C. of Illinois), .John M. Satterfleld (A. C. of 
Buffalo). G. A. Richardson (Intercollegiate Asso- 
ciation). Carl G. Fisher (A. C. of Indianapolis). 
Arthur T. Atherholt (A. C. of Philadelphia). 

Henry M. Neely was made chairman of the 
contest committee, and Arthur T. Atherholt chair- 
man of the press committee. Col. .Jerome II. .Toyce 
was elected treasurer ; .Jerome Fanciulli, secretary, 
and Geo. B. Harrison, field secretary. Harrison 
later resigned. 

By the terms of an agreement made between the 
Council and the Aero Club of America, the A. C. A. 
authorizes the organization of the "National Coun- 
cil of the Aero Club of America" and the A. C. A. 
is confirmed as the representative of the Inter- 
national Federation ; all matters relating to na- 
tional affairs' are to be referred to the Council, 
to be composed of one member from each affiliated 
club: the Council will construct an organization 
on the basis of state representation : the chair- 
man of the executive committee shall be named 
by the A. C. A. ; the matter of location of inter- 
national contests after the year 1910 vested in the 
N. C. ; a committee shall be constituted by the 
N. C. to deal with the question of sanctioning 
national meets, providing the A. C. A. agrees it 
will not make any agreements or contracts in 
national relations without approval of the N. C. 

SITUATION CUEIOUS. 

The situation is a curious one. As related 
previously in .Veronautics, the need for a na- 
tional body was felt and in response to letters 
signed by Hudson Maxim, president of the Aero- 
nautical Society, sent out by Thomas A. Hill, a 
large number of clubs signified their acknowledg- 
ment of such need and in the course of events a 
convention was planned at some central city at 
which a really national body would be formed. 

A temporary organization was formed under 
the name Aeronautic Federation of America to 
bring about this convention and to prepare drafts 
and plans for the proposed national body. 

Observing the apparent strength of this move- 
ment, the Aero Club hastily called a meeting 
of its affiliated clubs. The majority of the affiili- 
ated clubs responding to the call of the Aero 
Club were disgusted, and then and there, on 
May 23, formed the .\merican Aeronautical Asso- 
ciation. They found that the Aero Club was not 
willing fo give them anj' yolce in the affairs of 



the Aero Club of America and its affiliated clubs, 
and, as will be noted from the strong statement 
issued at the time, the new body was clearly 
against the policies of the Aero Club of America 
as exemplified in their action. 

Leaders of both the Aeronautic Federation of 
America and the American Aeronautic Association 
immediately got together and iilanned a joint 
con Vint ion to be held in New York, .June 22. 
L?()th organizations were to ass'emble in New York 
as many delegates of the clubs as possible. Both 
secretaries were to work in harmony and their 
letters were to be of the same general character. 
The Hotel Astor in New York was offered as a 
meeting place and accepted. The A. A. A. was 
advised that a meeting place had been secured, 
but unfortunately a misunderstanding had occurred 
and the A. A. .V. letters had called the meeting 
at the Waldorf. » 

TO WORK IN HARMONY. 

Previous to the June 22d meeting leaders in both these 
organizations got together and it was planned 
to call to order such delegates as assembled at 
either of the hotels, and then adjourn to a com-' 
mon meeting place. The .V. F: A. was called to 
order in accordance with the programme and ad- 
vised of the misunderstanding in regard to the 
hotels and it was with common consent that the 
meeting was adjourned and the deJegates in a 
magnanimous spirit proceeded to the Waldorf to 
meet in joint convention. 

A. F. A. DELEGATES SHUT OUT. 

The delegates who happened to come from the 
Astor experienced the greatest difficulty to being 
admitted to voting powers in the convention. All 
sorts of demands were made as to the form 'of 
credentials. Many credentials were "lost" by the 
credential committee. There seemed to lie a plan 
to keep these delegates out. It was also found 
that one of the delegates who was not empowered 
by his club to secede from affiliation with the Aero 
Club of America at the time the A. A. A. was 
formed, had sent out a day or two previous a great 
number of telegrams advising tliat the meeting 
place of the convention was at the Waldorf and 
not tlie Astor. with the apparent intention of 
stealing whatever delegates they might from the 
ranks of the A. F. A. despite the tacit agreement 
that both were working to the same end and in 
perfect accord. In response to these telegrams, 
many delegates who had been working with the 
A. F. A. went to the Waldorf. 

CONVENTION AT LAST DOWN TO BUSINESS. 

The session was a very strenuous one. and 
finally everything seemed to be working all right. 
The "delegates hiad all been admitted and pdace 
had reigned for at least 30 minutes. The whole 
day had been employed in seating the delegates 
and the body was now ready for business. A 
motion was made and carried to adjourn for 
dinner, to meet again at seven-thirty. 

One of the members of the Aero Club of America 
invited some of the delegates to dinner and a plan 
was laid at this meeting to withdraw from the con- 
vention at the evening session and retii-e to the 
-Vero Club of America. What mess of pottage the 
Aero Club could offer in exchange for the birth- 
right of the delegates is not apparent. At any 
rate, the scheme worked. 

When the meeting was called in the evening,

City, asked Lee S. Burridge, former president of

movers in the A. F. .\.. to take the chair while 
he was out temporarily. No sooner was the tem- 
porary chairman ready to receive motions than the 
delegate from the Pennsylvania Aero Club got up 
and withdrew his club from the convention. In 
rapid succession one-half of the other delegates 
followed suit, showing that the plan .so suddenly

,.J!uZi ™''" of self-respect could stoop to such 
methods as to place an innocent man in such a 
curious predicament, is difficult to understand 
It also developed at about the same lime (throuoli 
the a-iival of atteinoon newspape s) thit a cor- 
poiation had been formed at Albany under the 
name ot the American Aeronautic Association de- 
spite the tact It was agreed between the leaders 
a month previous that even the name of the 
proposed national body would be left to the ioint 
L'onvention to select. This showed a premeditated 
plan to steal the convention. Even some of the 
ielegates who met at the Hotel Astor, and who 
liad so much trouble in the morning- in bein"- 
idmitted to the ^yaldorf meeting, deserted the 
i-er.v ones who .started the whole movement, and 
xliich made a national l)ody i)ossible at this 

The organizers of the. A. A. A. were frankly 
)itter against the Aero Club of America and 
ret the.y joined hands with their enemy to the 
lesertion of their own comrades. 

WHERE IS THE N. C. OF A. C. A. AT? 

An officer of the Xational Council of the Ae"o 
lul) of America states that the Aero Club of 
Vmerica is now but a local clul) on the same 
tandmg with the others, that the Council will see 
o It that the club is kept in such position, that 
II the future the Council will rule and that the 
nly thing the Aero Club retains is its name and 
ts international affiliation, that the A C 1 is 
equired to represent the National Council' in 
iternational matters and to carry out its mission 
-that the A. C. A. is "down and out." 

On the other hand, it will be the chairman of 
tie National Council's executive committee that 
! named by the Aero Club of America ; the clubs 
ow forming the N. C, it is said liy the Aero

Club, are but affiliated clubs of the A. C A com- 
o^^ meekly into the fold after rebelling, and in 
added numbers; and the A. C. A. never had any 
afflHa^td clCbs°' '''''^' °^'' '^' ^"^ half-insurgent 
The one inference to be drawn from the situa- 
tion is that the Aero Club of America has deciu- 
edly increased its strength by inducing the clubs 
torming the National Council to become affiliated 
under the name of the Aero Club of America 
and by naming its own chairman. In return the 
A. C A allows the affiliated clubs now known 
as the National Council of the Aero Club of 
America to merely select the place of holding 
any national event which may be won by a repre- 
sentative of America.

" --.-•.•.•- .■ .V .jj^^^, ^^^ placed at rear of motor, both being 

mounted on the single upper member of the tri- 
angular body, the motor being also guyed to the 
lateral wing bars. Dimensions and control similar 
to the original "Demoiselle" with the exception 
of lateral control, in which the A'endome front 
flaps are used. Single surface cloth tacked on 
with tape. Lateral beams underneath as in the 
Curtiss and Pfitzner. 

On the whole, the machine lacked the finish and 
careful attention that characjterized the large 
monoplane built by Mr. Loose himself. The latter 
machine was exhibited without the motor Hs 
beautiful lines were admired by everyone. This 
was shown in the July issue. 

An "all-steel" monoplane was exhibited bv A. 
Soring, the ribs even being of small tu])ing 'Sur- 
face. 240 ft. Weight, 200 lbs. without power plant 
cloth or operator. Three-wheeled chassis, rear 
rudder turning with rear wheel, which also car- 
ries a supplementary surface, to the rear diagonal 
edges of which are attached the two separate flaps 
of the elevator. Lateral control by ailerons. One 
lever control. 

A most curious oddity was the exhibit of Israel 
Baylis ; it might appropriately be termed the para- 
dox of the show. Whereas all other exhibitors 
seeked to eliminate weight, in this case weight 
was a desirable factor. The model (see photo), 
about 2% ft. square, weighs 00 lbs. and has two 
wagon spring.s fixed to the base, between the ends 
of which (one on each side) is pivoted a heavy 
pendulum. This is to be driven, at a high speed, 
by gears and chains from the motor. The in- 
ventor claims that a reaction of the machine from 
the rapid pendulum blows on the spring ends, 
which cause it to lift. 

President J. C. Irvine of the Pacific Aero Club 
exhibited his battle-scarred balloon. "Queen of the 
Pacific." Capt. P. A. Van Tassel was early on 
the scene with a new 8,0O0-ft. dirigible, 14 ft. 
diameter by 63 ft. long. 

Gliders were exhibited by William Kreling. 
Ohrt Bros., M. Gunzcndorfer and J. Musser, C. 



The second annual aeronautic exhibition of th 
acific Aero Club from May 10 to 21, inclusive, at 
le Auditorium. San I'''rancisco, was a great suc- 
ss from an exhibition standpoint, the variety of 
achines giving a liberal education in aeronautics. 
one who had seen the first exhibition of the 
ub, it ga^e a startling idea of the marvelous 
ogress in the science in less than a year, and the 
emendous increase in public interest. At the 
st show there were but two comparatively crude 
achines — the latest show filled the hall and even 
truded upon the model flying area, several of 
e model flyers, disobeying their rudders, flew 
to the big machines lilce angry hornets and tore 
nts in their fabric. 

Two of the large aeroplanes exhibited had ac- 
iilly flown and attracted a large amount of in- 
•est on that account. They were the Curtiss- 
rring of Whipple Hall of the Pacific Aero Club 
d the beautiful large monoplane of George 
ose of the Pacific Aero Clul). The latter has 
t made extended flights, but is reported to have 
ared the ground for a short distance. 

The exhibits composed foiu- full-sized aero- 
nes (three monoplanes and one biplane), a bal- 
n, a dirigible, gliders, models, kites innumer- 
propellers. supplies and aeronautic acces- 
•ies and a United States signal corps portable 
reless set. 

A. novelty on the Curtiss was the .'Vft. exten- 
n of each end of the upper planes, as shown 
photo. This was an idea of Mr. Hall's : he 
ims that the additional surface (80 ft.) permits 
much slower speed in rising. The short beams 
wing bars fit into the end sockets and a bracket 
ces them to the end strut. 
The little "Demoiselle" monojilane. also exhib- 

I by Mr. Loose, was the hit of the show, its 
all proportions being somewhat startling to the 
itor. The body (not imported) was equipped 

Mr. Loose with an extra pair of skids at the 
r of the planes. Power plant : A 4-cvlinder 

II engine of 35 h. p.. 138 lbs., driving a" Coffin

Passenger car of the " Deutschland" Airship 

Sommer has delivered his first military aero- 
plane to the French army alter a demonstration 
flight of 2:10:00. 

PASSENGER AIRSHIP MAKES LONG TRIP. 

June 20. Leaving Friedrichschafen the new 
aerial liner "Deutschland" (Zeppelin VII.) sailed 
to Dusseldorf, a distance of about 311 miles, the 
trip lasting 9 hours. Count Zeppelin was in com- 
mand, and there were a dozen others on board. 
The new Zeppelin is similar to its recent prede- 
cessors, except that there is an inclosed gangway 
connecting the two cars and between them is the 
compartment for passengers. The walls are of 
mahogany covered aluminum and the furniture 
consists of wicker chairs. The length is 148 m. 
(485 ft.) and 14 m. in diam. The capacity is 
19.000 cu. meters.

June 24. The "Deutschland" undertook its Arstp. U^ ^ 
regular passenger trip, with a crew of 12 and 20 \i'^^ 
passengers. Throe hours were spent cruising ^ "^ 
around Dusseldorf. During part of the time there 
was wind and rain, but the elements seemed to 
have no bad effect. 

2775 MILES FLOWN IN A WEEK. 

June 25. Rouen meeting closed. The total mile- 
age flown was 2775 miles (4469 kil.) divided 
among various machines as follows : IT. Farman 
1095, Bleriot 900s -Vntoinette 713, Tellier 507. 
llanriot 489, Demoiselle 261. Sommer 411. Brcguet

flown without stop was by Dickson (II. Farman), 
141 kil., in 2 :2T :44. 

AIRSHIP "DEUTSCHLAND" DESTROYED. 

June 28. The Deutschland. carrying a crew of 
1-^ and 21 passengers, left Dusseldorf for a 3- 
hour trip. One of the propellers stopped after 2 
hours, and a storm rapidly came up. Findmg It

impossible to reach Mnnster, Osnabruck was made 
for. but as the ship had been in the ajr 9 hours, 
tlie gasoline supply gave out, and left the vessel 
at the mercy of the storm. It finally settled down 
on the trees of a forest, and the passengers es- 
caped with their lives. 

June 29. Lieut. Savoia made a cross country 
flight of 40 miles from Centocelle, Italy, and the 
day following one of 22 miles in his H. Farman. 

June 30. S. F. Cody tested his new biplane. 
The twin propeller system has been abandoned. 
Two engines have been fitted to drive a single 
propeller. Either can be operated individually. 
After making two circuits of Laffan Plain a gust 
of wind caused the machine to fall, and Cody 
vi'as pinned unconscious in the wreckage. The 
two engines are of the 50 h. p. 4-cyl. Green type. 

Jllne .30. Labouchore (Antoinette) and C. L. 
W^achter^ (Antoinette) flew from Mourmelon to 
Betheny for the meeting there. 

July 2. The Wolverhampton. England, meet 
closed. Grahame-White ( Farman ) was longest in 
the air in one flight, 1:15:38: L. D. L. Gibbs 
(Farman) second with 1 :13 :5. 

$5,000,000 FOR AVI.\T10X. 

July 2. The Italian Chamber of Deputies has 
granted about .$5,000,000 for construction and 
maintenance of aeroplanes and airships. 

FUEXCH EXTllIES FOR IXTERXATIONAL. 

July 3-10. Seventy-six entries in the Rheims 
meeting. Monoplanes entered, 29. Leblanc, 

Latham and Labouchere were picked to represent 
France in the international at Mineola, L. I. In 
Leblanc's flight he broke the 5, 10, 50, 60, 70, 80 
and 90 kil. speed record. 

BARONESS MEETS WITH ACCIDEXT. 

July 8. Baroness de la Roche met with an 
accident at the Rheims meet, suffering severe in- 
juries. She had apparently become unnerved by 
the close passing of two other aeroplanes. One 
of the passing aeroplanes flew directly over her, 
and it is thought that the draft from its pro- 
peller made trouble for the baroness. 

GRAHA.ME-WHITE FLIES 90 M. CROSS COUNTRY. 

July 11. Grahame-White flew a distance of 
901/2 miles in to the Bournemouth aviation grounds 
where a meet was in progress, in 2 hours 35 min- 
utes. On .July 7 he started from Loudon to make 
the entire distance, but an accident compelled him 
to land after going but a short distance. 

BRITISH ALTITUDE RECORD. 

J. A. Drexel made two ascents on July 11 at 
the Bournemouth meet of 1950 and 2493 feet alti- 
tude in his Bleriot. On June 20 he went up ti> 
1070 feet. 

New Prizes Abroad. 

The London Daihj Matt has announced the con- 
ditions for its new .$50,000 prize. The contest is 
open to the entire world, to be held the second 
week of July, 1911. The winner will be he who 
starts from a fixed point near London and com- 
pletes a l.OOiO mile course laid out over various 
cities iii England and Scotland, and making a 
complete tour of Great Britain. 

The Automobile Club of France offers a $30,000 
"(Jrand Prize" for an aeroplane flight from Paris 
to Brussels and return, divided between the three 
who cover the course in the fastest time before 
January 1, 1911, the machine to carry two people, 
or two with ballast enough to make up a weight 
of 150' kgs. Must be made within 36 hours, start- 
ing from Issy. One descent at Brussels is obli- 
gatory. To take not more than 3 hours. 

$10,000 is offered for dirigibles over a course 
Paris to Rheims and back, given to the pilot 
making the best time before January 1, 1911. 
Start and finish at Vincennes. One descent obli- 
gatory at Rheims, where an extra passenger must 
be taken up of a weight of 75 kgs. Duration of 
landing counts as part of the time. 



M. Lazal-e Weiller, who was connected with the 
French Wright Syndicate, has offered the Wal- 
Minister of France a $5,000 prize for a dispatch 
carrying competition lietween military aviators, 
carrying a passenger. 



The H. Farman instruction biplane covers prac- 
tically every day a total distance of 200 kils. with 
two on board. 



AEROPLANE RISES FROM WATER. 

Henri Fabre. with a monoplane of 50 h. p.. 
Gnome engine, mounted on 3 hydrocurves, has 
been able to fly a distance of 5 kils., rising and 
alighting on the water. The speed attained was 
100 k. p. h. The speed is 14 m. 



One hundred and eleven aviation pilots here 
received licenses from the Aero Club of France. 
These are divided among various makers of ma- 
chines, as follows: iMme. de la Roche is the 
sole woman pilot.) 

Bleriot 24 ; Curtiss 2 : R. F P. 1 ; II. Farman

Aeroplane and Airship Casualties. 

VICTIM OF ms OtVN COURAGE. 

June 18. Thaddeusi Robl, ^ho learned to fly a 
Farman, was killed at Ste-tWif, (Jermany. The wind 
was blowing and no aviator would fly. The crowd 
became angered, and called for Robl. who at- 
tempted a flight. Descending from a height of 2(io 
feet, a gust caught him and he was buried undi'r 
the wreckage, with his neck broken. He expired 
in a few mom^nt_s^

the ground from a considerable height. 




Oscar Erbsloh 

DIRIGIBLE explodes. 

On July 13. Oscar P^rbsloh, the winner of the 
Bennett balloon cup at St. I.,ouis. 1907, with four 
companions fell from the non-rigid dirigible "Erbs-

loh" when it was at a height of over 900 feet 
The cause is stated to be the bursting of one of the 
ballonets. It is thought possible that the expan- 
sion of the gas at the high altitude caused the 
bag to burst. 

The airship had a cubic volume of 290O cubic 
meters, was 53.2 meters long and 10 m. diam., 
driven by a 125 h. p. Benz motor. The speed was 
29 m. p. h. and could carry 6 people. The pro- 
peller was forward, of 2 blades, and 4.5 meters 
diam. 

DE-Vjat—ttF ROLLS. 

The Hon. C. S/Roll^ met with his death at 
Bournemouth, Eng.>sjjil^l2, while flying his Short- 
Wright machine in a contest for landing nearest 
to Si predetermined spot. Just what happened it 
is impossible to determine at this moment. The 
motor had been shut down previous to the glide 
down. 

The Hon. C. S. Rolls, son of Lord and Lady 
IJangattock, has been one of the foremost in aero- 



Augusi, igio 

nautic sport. When the automobile came into 
being ho was an ardent supporter, winning several 
races. He has made more than a hundred balloon 
ascents, and last ,year took up the aeroplane. 
Recently he jumped to the front with hour flights 
and more, crossing the English Channel and re- 
turning without stop.

THE NEW FARMAN MONOPLANE 




Henry Farman has begun trials with a new 
monoplane. The spread is 23.6 ft., depth 6 ft. 6 
in.; the tail measurements are 9 ft. 10 in. by 
3 ft. 3 in., and the overall length of the machine 
is 26 ft. 2 in. The supporting surface is practic- 
ally 190 sq. ft. So far as can be gathered from 
examination, the wing curvature is the same as for 
the standard biplanes. The tail is 9.8 ft. by 3.28 
ft. The total weight of the new machine is given 
as 6G0 lbs. 

Lateral stability is secured by two ailerons of 
the familiar Farman type. The Farman is the 
only successful French monoplane employing aile- 
rons, the Antoinette having abandoned them in 
favor of flexing the wing, Bleriot, Tellier and Han- 
riot never having employed them. The horizontal 
tail member has one half of its surface fixed 
and the rear i)ortion hinged to form an elevator. 
On the more recent biplanes the extremity of the 
upper tail member has been made pivotable, to 
operate in conjunction with the front elevation 
rudder, but this movable surface was only about 
one quarter of the whole ; on the monoplane it is 
half the depth of the plane. The rudder is 
mounted entirely above the horizontal plane, and 
had ahead of it a triangular shaped pin. 

The fuselage is a triangular structure imited at 
the forward end by steel girder work in the form 
of a cross, the center of which serves to receive 
the mounting of the fixed shaft of the (inome 
motor. The four main frame members are united 
by suitable stanchions, and trussed with piano 
wire; they ar»> not united at the rear. The wings 
are not mounted directly on the fuselage, but i\rc 
carried almost two feet above it. This places the 
pilot, the motor, and the petrol and oil tanks on a 
lower plane than the bearing surface. A trian- 
gular structure receives the wings, and at the 
same time serves for the attachment of the run- 
ning gear. 

At right angles to the longitudinal frame mem- 
bers are two vertical members, attached to the 



Vhotn hii F.ihrin Levick, N. Y. 

steel girder work on the fore end of the fuselage, 
and mounting aliove the level of the wing and 
descending considerably below the level of the 
frame. From the lowest point of these two "up- 
rights are two similar members inclined towards 
the rear, attached to the two longitudinal members 
of the fuselage, and receiving on their upper ex- 
tremities the rear transverse girder of the wing. 
This, as can readily be seen from the illustration, 
forms a triangle— or really two triangles, one at 
each side of the fuselage — the apex of which is 
near the ground, and receives the axle of the 
running wheels and the base above the main 
plane. 

The rear plane is mounted directly on the fusel- 
age, with the hinged portion overhanging in order 
to allow free movement. The rudder and fin are 
mounted above the fuselage, and consequently 
above the horizontal plane. There are neither 
shock absorbers or skids, the aeroplane starting on 
two small diameter pneumatic-tired wheels mount- 
ed on a steel axle passing through the points of 
th<' two triangles already described. Towards the 
rear of the aeroplane is a simple type of skid to 
prevent the tail from trailing On the ground. The 
|)ilofs position is within the fuselage, just to the 
rear of and below the level of the wing. 

The fuselage is not encased. The motor, of 
course, is in the usual position ahead, overhang- 
ing the extremity of the fuselage. It is the stand- 
ard type of Gnome, with a two-bladed Chauviere 
propeller. Placed below the level of the wings, 
the jiilot has the advantage of being able more 
correctly to estimate his distances for landing 
than is possible when carried slightly above the 
wing level. Furth(n-. this advantage is gained 
without any loss of protective material in case of 
a rou-rh handling, there still being the motor and 
half the length of the fuselage ahead, the wings 
on each side, and the running gear below, to 
take the shock before the pilot can be reached. 
The machine's first appearance in competition will 
be interesting.

International Aviation Tournament at 
Mineola. 

The national and international aviation meet- 
ing for lyio will be held near Mineola, L. I., 
about one mile east of the present aviation field, 
beginning Oct. 15 and closing Oct. 23. The inter- 
national speed contest for the Gordon Bennett 
trophy will take place on Oct. 22. 

For this contest there will be at least 11 com- 
petitors — three from France, three from England, 
one from Italy and three from America. Elimina- 
tion races for the selection of the French team 
were held in Rheims, July 5, when Latham, Le- 
blanc and Labouchere were chosen. Latham uses 
an Antoinette and the other two Bleriots. 

Grouped about the international speed champion- 
ship contest will be an interesting program of 
events, including many novelties and extraordinary 
feats for aeroplanes. This program is now being 
arranged, and will be announced as soon as pos- 
sible. Cash prizes amounting to about $50,000 will 
be awarded for the most important achievements, 
with several special prizes for other events. 

Contracts are soon to be awarded for the build- 
ing of the grand stands, aerodromes, etc., and 
the field, two and one-half miles in length by 
one mile in width, is now being put in proper 
shape. 

In addition to the regular challengers for the 
International trophy, it is expected that a large 
number of foreign and American aviators will take 
part in the general program. Inquiries have al- 
ready been received from many European aviators, 
and no doubt many machines will actually fly over 
the course during the meet. It has not yet been 
determined who the American cup defenders will 
be, but it is expected that Glenn H. Curtiss. win- 
ner of the trophy last year, will be one of the 
three. 

Lawrence L. Gillespie of the Aero Club of 
America, chairman of the subscribers' committee, 
reports good progress in raising the $250,000 neces- 
sary to finance the meeting. The committee has 
appointed Gage E. Tarbell as general manager and 
Byron R. Newton as assistant manager, with offices 
at 320 Fifth Ave. Announcement of the prizes 
and program will soon be made. 

Aviation Treaty Between Mexico and the 
United States First of Its Kind. 

By E. L. Ramsey. 

THE Foreign Office confirms the statement that 
negotiations are under way for the celebra- 
tion of a treaty between Mexico and the 
United States for the purpose of regulating aerial 
traffic over the border line of the two countries 
with the special view of preventing smuggling. 

So within a short time it will be illegal for an 
American to visit Mexico in an aeroplane or dirig- 
ible balloon, because it would violate the treaty 
which is being negotiated between the United 
States and Mexico. 

Charles K. Hamilton has already crossed the 
Rio Grande at Ciudad Juarez and El Paso in an 
aeroplane, and the long fliglits that are now being 
made are sufficient notice that such events will 
not be remarkable in the future. This makes It 
necessary for the two governments to extend the 
provisions of their treaties regarding immigra- 
tion and the collection of customs duties so that 
inspections may be made In the interior as well 
as on the border. 

The officials of the State Department have made 
many favorable comments on the advantages to 
be derived from such a treaty. 



.\MERIC.\XS 10 FLY IN MEXICO NEXT FALL. 

Joseph Hidalgo and Sparks M. Berry, of Los 
Angeles, have made proposals to take part 
in the centennial celebrations in Mexico City this 
tall. They propose to bring a number of aero- 
planes, with expert aviators, dirigible balloons and 
several aerostats. This has given rise to new 
hopes on the part of Governor Lie Landa y Es- 
candon of the Federal District to make this one 
of the drawing cards of the event. 

The matter will be discussed by the national 
centennial committee, of which Mr. Landa y Es- 
candoa is the president, at the next meeting, and 
no reply will be given to either of the proposals 
until then. 

Terms of Chicago-New York Fhght An- 
nounced. 

Dates have been set for the contest to be held 
under the auspices of the New York Times and the 
Chicago Evening Pout from Chicago to New York 
for a prize of $25,000. The race will start Oc- 
tober 8 from the Windy City. 

A resume of the conditions follows : Enti-ies 
may be made at any time after publication of the 
terms. There must be at least ihree competitors 
or no race. The start shall be 10 o'clock a. m., 
or as soon thereafter as may be, and shall be 
simultaneous, if possible. In case of uad weather, 
the start may be postponed from day to day until 
Oct. 15. Each entered machine must be in Chi- 
cago by Oct. 3 and give daily trial Uights until 
start. The race must be finished within 168 
hours from the start. Stops unlimited. Each en- 
trant must have a verified record ot one hour s 
continuous flight in Chicago between Oct. 3 and 8. 
Repairs may be made en route, but aviators must 
finish in the same machines they make the start. 
If the start is simultaneous, the lirst machine that 
reaches the finish vk'ithin the rules will be ad- 
judged winner, but in case the entrants start at 
intervals, due allowance will be made. A flight of 
equal or of greater length than the proposed course, 
prior to the race in this country, shall serve to 
invalidate its terms. The promoters of the event 
reserve the right to delegate the management of 
the affair to a recognized aeronautical society if 
such a course is deemed advisable. 

Public school 77 of New York celebrated a 
"safe and sane" Fourth by having a free balloon 
ascension in addition to kite contests. It was not 
intended to be of the free variety, but the bag 
took charge of itself and sailed over to Mas- 
peth, L. I. 

An 18-ft. balloon was furnished by A. Leo 
Stevens and a generating plant was installed in 
the Central Park yard at 97th St. After infla- 
tion was complete, the balloon was guided over 
and under trees in a brisk breeze, up Eighth Ave. 
to lOGth St., sustaining small holes in the Journey. 
These were patched up, and the balloon, decorated 
with flags, was sent up at the end of a 2,0O0-ft. 
rope. In pulling the balloon down in the late 
afternoon, the rope broke and the balloon slowly 
went out of sight. Not being quite full, there 
was ample opportunity for the gas to expand. 
When found, it showed signs of having burst 
at a great altitude.

St. Louis Aero Show. 

That exhibits of complete aeroplanes and motoi's 
built expressly for aerial use will be the feature 
of the St. Louis National Aero Show, in the 
Coliseum, Oct. S to i;!, is now assured by con- 
tracts for floor space which have been made by 
several well-known coneoms, among them the 
agents for the Gnome motor, to which Paulhan 
and L'arman attribute much of their success. 

Complete aeroplanes and a new aero motor will 
be shown by the Aerial Navigation Co. of Girard, 
Ivans. This concern has already completed three 
machines of the same type, which are reported to 
have been sold, and has now constructed three 
more. 

The Aeromotion Co. of America (St. Louis j has 
taken space in which to exhibit the Gnome motor, 
and lias reserved additional room for exhibiting 
two types of foreign-made aeroplanes for the 
agency of which they have about completed nego- 
tiations. Marc Seguin of the Aeromotion Co. 
cabled to the t'rench house of Gnome motors before 
taking space and learned that the company could 
furnish a motor for exhibition at the time of the 
show. It will probably be the tirst Gnome motor 
siiowu in St. Louis. 

Another type of rotary motor, which works upon 
practically the same principle as me r'rench-made 
Gnome, will be exUioited by the nolmes Kotary 
Motor Co. of Denver, Colo. The western Oil 
i'ump and Tank Co. (St. Louis j has tauen space, 
and will exhibit its regular line ol laniis and self- 
measuring pumps, but in addition 10 this, it is 
rumored that this company will show something 
novel in the way of an aei-ial accessory which will 
be of considerable importance to airmen. 

The Aeronautic Supply Co., which has just 
opened a store on Olive St. ia the heart of the 
automobile district, will be another St. Louis ex- 
hibitor, showing practically everything for the 
construction of complete planes as well as the tin- 
ished machines. Tuis concern has already placed 
St. Louis in an important position as far as the 
aeronautic industry is concerned. It was the first 
aeronautic supply house in America, and it is said 
that its present number of clients is 3,000 people, 
embracing the entire country, Canada and Mexico. 

The eight or ten airmen about to take part in. 
the novice meet of the Aero Club of St. Louis are 
very much interested in the coming aero show, 
and have expressed their intentions to have ex- 
hibits there, provided they are successful in their 
work this summer. 

Hamilton Tries Two Cycle Engines. 

Charles K. Hamilton, who has split with Cur- 
tiss, has borrowed for temporary use the Curtiss 
type aeroplane built by Fred Shueider for G. E. 
DeLong of the Elbridge Engine Co. of IJochesier, 
and expects to use it in demonstration flights at 
Mlneola until his own high-powered racing ma- 
chine is completed, which will probably be the 
lirst part of August. The De Long machine is 
equipped with an Elbridge two-cycle 40-t;0 h. p. 
engine, Bosch magneto and Requa-Gibson pro- 
peller, El Arco radiator and Harttord tires. This 
is the same machine which Dr. Greene flew at 
Rochester. 



C. W. Bennett, who was associated with Messrs. 
Wilcox. McDonald and Carruthers in getting up 
the Montreal meet, h,as disposed of his interests 
and has joined hands with the Aviation Co. of 
Canada. 

The Aviation Co. of Canada has been organ- 
ized with oftices at 201 St. Catherine St.. Mon- 
treal, with the primary object of promoting so- 
called "meets," supplying fairs, etc., and has 
secured representation in the maritime provinces 
and the west.

Rules for $15,660 Prize. 

The rules for the Edwin Gould $15,000 prize 
have been formulated, and are, in short, as fol- 
lows :

Kite Contests at Mineola. 

Edward Durani is directing kite flying and 
model contests every Saturday at Mineola. Two 
score boys started the rtrst of the series on July 
•4th for a cup ofl'ered by Mr. Durant. At the end 
of an hour many of the kites had escaped and 
the contest was brought to a close. The three 
prizes went to Frank Krug, John Kinsella and 
Carl Morehouse respectively. 

Pennsylvania Club Has Grounds. 

The Pennsylvania Aero Club is building six 
sheds at Clementon, N. J. Edward Augsberger is 
working on his machine in one shed, the Lesh 
aeroplane belonging to Herbert Ilazzard is another 
and Louis Bergdoll who bought a Bleriot some 
time ago will probably use another shed. A meet 
is in anticipation for the Fall. 

Armour Institute's Aero Course. 

The rapid development of aerial navigation has 
led the Armour Institute of Technology to offer 
instruction in the more important branches of 
this subject. The object of the course is to pre- 
pare students for experimental and practical work 
in aeronautics. 

The elements of what is known of the scientific 
principles upon which the art of flying is based 
are taught. Students are made aciiuainted with 
the work and results of the principal experiment- 
ers ; and also with the methods of construction 
now used in successful air ships and aeroplanes, 
including motors. These courses are elective and 
open to Juniors and Seniors of all departments. 

The subjects of instruction are : 

.\ERODYXAMICS. 

The work in this subject includes the study of 
fluid resistance, stream line forms, the economics 
of flight, the theory and efficiency of the screw 
propeller, and experimental aerodynamics. Pub- 
lished accounts of experiments, including the latest 
available, are drawn upon for data on which to 
base mathematical studies of the problems of 

Text-book : Lancaster, Aerial Flight, Vol. I. 
Aerodi/nainicf<, supplemented with lectures. 

Two hours per week during the second semester 
of the Junior year. 

.\KKO.\AUTICAL DESIGNING. 

The studies include the stresses in the principal 
tvpes of balloons, air ships, and aeroplanes now 
in use ; and the designing and detailing of these 
structures. 

Lectures with problems assigned for solution

Death of A. L. Pfitzner. 

Ai L. Pfitzner, who was employed by G. II. Ciir- 
tiss to design the present 4-cylinder Curtiss engine, 
then building and flying a monoplane of his own 
and later experimenting with the Burgess aero- 
plane at Marblehead, Mass., on July 12, went out 
in a boat and shot himself, falling into the water. 
The boat was found adrift. In it was his hat 
and coat and a note asking the finder of the boat 
to return it to its owner. The reason for his act 
is thought to be despondency. His loss is keenly 
felt by all those who knew him. 

Mr. Pfitzner had been fairly successful in flying 
the Burgess aeroplane, and had made numerous 
flights on his own machine, as recorded in Aero- 
nautics. On July y he made a flight of about ."J 
miles. When directly over the river at IMum 
Island, where all of the flights are being made 
with the Burgess machine, a gust of wind hit the 
machine and both the aviator and the aeroplane 
landed in the water. 

On July 8 he made a flight of a couple of miles 
and then landed, due to the overheating of the 
engine. 

Meets Death in Glider. 

Eugene K. Speyer, of San Prancisco, Calif., a 
young lad student, who with his "pal," Carlton 
Gray, had built a biplane glider, was killed on 
June 1 during his first experience at gliding, 
while towed by an automobile. Evidently fright- 
ened by the speed and a contrary gust of wiud, 
he turned his front rudder down and the machine 
hit the ground and turned a somersault, breaking 
the boy's ribs and resulting in his death a few 
minutes later in the hospital. Speyer was quite 
insistent on being the first to try the machine 
and would not even toss a coin for choice. 

The Wright Suits. 

New York. July 1. The U. S. Circuit Court 
of Appeals yesterday denied the motion on behalf 
of the Wright Company asking that the Curtiss 
concern put up a bond to protect the petitioner 
from loss in the event of winning the patent 
suit. The petition sets forth the loss being done 
the Wright Company by the flights of Curtiss and 
Hamilton and others using Curtiss machines. In 
the last issue the dissolution of the injunction 
against Paulhan and Curtiss was announced. 

The suit against Saulnier has been dropped as 
he left the country. Pressure of work that has 
seemed more important has prevented suits being 
brought against Harmon and other alleged in- 
fringers but the matter is not being held open 
awaiting final decision on the original suits. The 
Wright Company in the near future will proceed 
against every infringer who is injuring its busi- 
ness. 

The Wright Co. hns filed a demurrer to the 
action brought by Charles Lamson alleging in- 
fringement, stating that the bill of complaint 
does not show whether the infring-emeiit was com- 
mitted by the defendants jointly or severally, 
and that it does not aver execution of the letters 
patent according to law.

Balloon Races Off. 

The balloon race scheduled at Peoria, July 5-0, 
was called off. A storm upset the plans for the 
St. Louis race on June (J-T and the balloons had 
to be deflated to save them. 

Octave Clianute, who was taken ill in Paris 
last month, is reported in a cablegram to his son,

Flying Machines: Con- 
struction and Operation, 
is a new book announced 
by the Charles C. Thomp- 
son Co., of Chicago. It 
will be ready for distri- 
bution June I. The au- 
thors are W. J. Jackman 
and Thos. H. Russell, 
both well known as 
writers on mechanical 
topics. Octave Chanute, 
C. E., a recognized au- 
thority on aviation, con- 
tributes a chapter on 
"Evolution of the Two 
Surface Flying Machine," 
which will undoubtedly be of interest and 
benefit. 

While many valuable works on aviation are 
in circulation, the preliminary announcement 
of "Flying Machines : Construction and Opera- 
tion," makes plain the fact that this is some- 
thing different. In the words of the publishers 
it is a "show how" book for novices who wish 
to construct and operate flying machines. With 
this purpose in view it is strictly non-technical 
and easy to understand. 

For sale by Aeronautics at $1.50 in leather; 
$1.00 in cloth. 

Les /Aeroplanes de 1910 by R. de Gaston, sec- 
retary of the French Society of Aerial Naviga- 
tion. Preface by M. J. Armengaud, and a 
study on propellers by M. V. Tatin. Librarie 
Aeronautique, 32 rue Madame, Paris. Price 4 
fr. 

A technical study of the principal aeroplanes 
of 1910, usually showing drawings, which gives 
in brief space very complete data, figures, 
scales and comparative tables. This is a work 
of real value to the experimenter and to the 
student of aviation. 

The Sky-Man is the title of a new and ab- 
sorbing book just brought out by The Century 
Co., New York. A pleasure yacht goes up 
into the wilds of the frozen North, searching 
for some signs of a lost vessel which con- 
tains an Arctic explorer and his party. On 
board the yacht is a young girl. Jeanne Field- 
ing, the daughter of that explorer. Up into 
the same region of the North comes a young 
man, Philip Cayley. who has long been an 
outcast from civilization, because of a crime 
of which he was not really guilty. He has 
taught himself to fly with a pair of giant 
wings whose motive force is the muscular 
power of his own body. Wild chance and a 
quick succession of stirring adventures leave 
the "sky-man" and the young girl alone to 
fight privation and darkness through an Arctic 
winter. Of course, there is a villain in the 
case, a half insane Norwegian sailor, whose 



stealthy appearances make life miserable for 
Philip and Jeanne. 

It is a book which appeals to the imagina- 
tion — a story not sociological nor with a prob- 
lem in it, but of the kind of adventure that 
one finds in "Robinson Crusoe" and "Treas- 
ure Island." For sale by Aeronautics at $1.30. 

The Epitome of the Aeronautical Annual. Mr. 
James Means, who pul)lished the "Aeronautical

Lighter Gas for Balloons. 

A new German invention of value for free bal- 
loons is reported by Consul Tbomas II. Norton of 
Chemnitz : 

Illuminating gas is foreed through long tubes, 
maintained at a very high temperature. Most of 
the carbon in the hydrocarbons is thus separated 
out and the percentage of hydrogen is largely in- 
creased, so that this gas constitutes 8U per cent of 
the modified coal gas. At the same time it is 
deprived almost entirely of its characceristic odor, 
and freed from the presence of benzine, which 
exerts an undesirable solvent action upon the mate- 
rials employee to render balloons impermeable. 
The most important change is that in buoyancy, as 
the specitic gravity sinks from 0.44 to 0.2i;5, or less 
than one-quiarter the weight of air. This means 
that 1 cubic meter of the new gas can support 
a weight of 1 kilo (2.2 pounds J. In coal gas, 1 
cubic meter supports 0.7 kilo. A balloon with a 
capacity of 7,000 cu. ft., when inflated with the 
new gas, has a lifting pow'er equal to that of a 
balloon of 10,000 cu. ft. charged with ordinary 
coal gas. 

Wellman in the Air Again. 

It has been announced that Walter Wellman 
and Melville Vaniman, who have made a numbi-r 
of attempts to reach the pole by airship without 
success, are now planning to sail from Europe to 
the States in the same ship, "America," used in 
previous expeditions. The London Telegraph and 
the New York Times are exploiting the attempt, 
agreeing to purchase all the news which Mr. Well- 
man can produce.

The Call Aviation Engine. 

A decided refinement in aeronautic engine con- 
struction is that adopted by the Aerial Navigation 
Co. of America, with laeadrjuarters at Girard, 
Ivans., in the Call aviation engine. 

This is a regular opposed two and four cylinder 
engine of the usual four-cycle type, water cooled, 
G-in. bore by 5^/4 -in. stroke; the two-cylinder en- 
gine developing 50 horsepower and the four- 
cylinder engine developing 100 horsepower at 1,900 
revolutions per minute. 

It is in the cylinder and cylinder head con- 
struction that the chief point of interest lies. 

Even with the usual copper or other sheet metal 
water jacket, adopted by most aeronautic engine 
manufacturers to lighten the weight of iron cyl- 
inders, the great weight of cast iron either com- 
pels an unduly thin cylinder in order to keep 
down the weight, or, in case the cylinder walls are 
made of the requisite thickness for strength, the 
engine becomes very heavy.

AERONAUTICS 



On the other hand, the employment of steel 
for cylinders, as has been attempted by certain 
manufacturers, both in tliis country and Europe, 
has not, to say the least, met with signal .success. 
Whether from the extreme thinness of the cylinder 
walls or to steel being less satisfactory in its 
bearing qualities than gray iron, engines of this 
construction, wliile giving satisfactory short runs, 
have failed in endurance tests. 

In the Call engine the cylinder walls, piston 
heads, valve cages, valve seats, as also all other 
iiarts exposed to the heat of explosion chamber. 
nre constructed' of a special liigh-grade vanadium 
uvnv iron, while tlie outer cvlinders and cylindcn' 




heads, comprising also the water jacket, are con- 
structed of a special high-grade alloy of aluminum 
and magnesium called magnalium. 

UnJike other constructions In which the use of 
an outer cylinder of lighter metal with an inner 
cylinder or bushing of gray iron has been at- 
tempted, it will be observed from the accom- 
panying illustrations, first, that the iron inner 
bushing is surrounded throughout its entire ex- 
plosion chamber length by the jacket water, with- 
out any intervenin'j- metal or joints, and. second, 
that no part of the lighter metal of which the 
outer cylinder and cylinder heads are composed is 
eyjiosed to the heat of explosion chamber. 

With proper water circnlation, all danger of 
the overheating of the outer cylinders is thus 
avoided, and the proper adjustment maintained 
between the relative heat conductivity and ex- 
pansive qualities of the two metals. 

The gray iron bushings are machined to a per- 
fect fit both inside and out. and are then pressed 
into the outer cylinder from the top. These bush- 
iii-;s are of ami)le thickness throughout the length 
(if explosion chamlier. and' below that are consider- 
ably reduced in thickness. .\s will be seen from 
Ihe accomiianying illustrations, an additional 
shoulder upon the inner cylinder at the top is 
machined to fit into a companion groove in the 
iragnalium cylinder in order to make a thor- 
oughly watertight connection, while the spiral 
uartitions of the magnalium water jacket extend 
inward to the iron cylinder, greatly strengthening 
it 1o resist the explosive stress encountered. 

By the use of this lighter metal for the main 
miter cylinder, enormous strength of construction 
is permitted without undue weight. The magnalium 
cylinders are. in fact, of sufficient thickness to give 
a tensile strength of something lik(> 150.000 lbs., 
while the cylinder base and cylinder heads are 
each secured by a dozen steel studs or cap screws 
% in. In thickness, having a combined tensile 
strength of 150.000 lbs. 

In order to further lighten the engine, the valve 
cages, which are also of vanadium gray iron in 
one piece, are air cooled above the level of the 
cylinder heads: while below this and around the 
valve seats they are most efficiently water cooled. 
The crankcase and' fittings not exposed to the heat 
of explosion chamber are also made of magnalium. 
similar to the material used for outer cylinders 
and cylinder heads, and the crankcase is thor- 
oughly braced and ribbed in such a way as to 
give enormous strength combined with minimum 
weight. 

Having thus secured lightness in the heavier 
engine parts, there has been no attempt made upon 
the part of the designer to secure lightness by 
the use of freakish material and insufficient sizes

iu the construction of piston heads, connecting 
rod's, cranlvshaft and other lilce parts. The piston 
h( ads and rings are also made of van.adium gray 
iron. The connecting rods are the best grade of 
vanadium phosphor bronze, specially designed for 
strength, and the cranlishaft is of the best grade 
of vanadium steel, solid throughout. 

The valves are of large size and have unusually 
large valve lifts. Both the inlet and exhaust 
valves are 2 in. in diameter, and the valve lift is 
% in., giving free clearance. In addition to the 
main exhaust valves, a ?4-in- (inside diameter) 
auxiliary exhaust port, thoroughly water cooled, 
is placed on the bottom side of each cylinder. 
This exhaust port is allowed to open somewhat in 
advance of the main port, and thus draws the 
tire, furnishing an additional safeguard against 
the overheating of the main exhaust valve seats 
and bearings. 

Roth the main and exhaust poi'ts are silenced, 
not by means of the usual baffle and muffler plates, 
which crowd the e.xhaust back into the explosion 
chamber, but by a special silencer constructed of 
an inner casing of steel tubing, with V slotted 
mouth, over which an outer casing of aluminum 
tubing of considerably larger proportions is then 
litted b.v means of a vanadium gray iron ring or 
thimble containing a large number of holes around 
its entire circumference. The force of the exhaust 
l)um))s the cold air through these openings, and 
by this means the gases are so cooled and shrunk 
by the time they reach the mouth of the silencer 
as to greatly diminish the deafening noise so 
Iironounced a feature of other aviation motors.

Especial attention has been devoted to securing 
the greatest possible cooling facilities. To this 
end the water jacket partitions are spirally ar- 
ranged in such a manner that the .iacket water 
passes four times around the cylinders during 
each circuit, and then over the entire surface of 
the cylinder heads. In addition to this, the en- 
gine is also equipped with a piston circulation 
pump instead of the usual centrifugal or gear 
pump adopted on automobiles, and copied by other

aviation engine manufactuvers. Tliis piston pump 
is positive in its action, and in connection with 
the spiral cooling flanges forces the .jacket water 
four times around the cylinders during each 15 
seconds. 

While the manufacturers of this engine have en- 
deavored to put upon the market a moderate priced 
engine, they have spared no pains and expense to 
make the engine of the very best quality, both in 
the character of its workmanship and finish. All 
the exposed parts of the engine not constructed 
of magnalium — a shining non-corrodible metal — 
are nickel plated, and the whole engine is polished 
to a mirror (inish. The demand has been so large 
that the manufacturers have been compelled to 
increase their shop and foundry facilities fi'om 
time to time, until they are prepared to supply 
the engine on short notice and in any numbers. 
The prices of the above engines are $1,000 for 
the m h. p. and if 1.700 for the 100 h. p. respec- 
tively. These prices include all accessories, such 
as carburetor, pump, ignition and radiator 
facilities. 

Two Spark Plugs to a Cylinder. 

Messrs. Unterberg & Helmle, who make the 
famous I'. & n. Master magnetos, have developed a 
new type of magneto, which meets with every re- 
(juirement of speed service. In this new U. & H. 
i-acing magneto, two tarmatures are employed 
mounted tandem, and running in the same arma- 
ture tunnel on one shaft. These armatures arc 
fitted with two complete sets of windings, each set 
consisting of a primary and secondary winding. 
The most unusual feature of the magneto lies in 
the fact that but one interrupter is employed to 
break the primary circuit of both armature wind- 
ings, and it is obvious that this arrangement must 
produce the high tension current in each arma- 
ture winding, and must produce these two impulses 
at precisely the same instant. 




TWO PLUG.S FOR EACH CYLIXPER. 

The magneto is equipped with a compound dis- 
tril)utor, each armature winding being connected 
liy conventional means with the distributor. One 
set of plugs is connected with one distributor, 
and the otlier set of plugs, of course, connects 
with the other distributor. Two safety spark gaps 
arc jn-ovided, one for each high-tension circuit, so 
as to eliminate any danger of damaging the wind- 
ii)L;s. should the cables, leading to the plugs, be 
a (I i dentally damaged. 

As will be seen, the above uniciue arrangement 
n\( rcomes all objections heretofore found in the 
Use of two magnetos on racing motors. It is im- 
nialirial as to the amount of wear which takes 
lilace in the driving mechanism, or the amount of 
wear on the inferrujiter mechanism of the mag- 
neto, as the one break of the magneto interrupter 
operates for both windings. It is impossible to de- 
range the magneto so that one set of plugs will 
receive the electric impulse before the other does, 
and tests made abroad with this new type of mag- 






TO THE PROMOTERS OF THE 

Coming Aeroplane Meets 

You want exhibitions of Man-Lifting- 
Aeroplane Kite Flying to interest the 
crowds while the aviators are not flying. 
C High or even moderate winds will in- 
variably keep the aeroplanists from flying 
until late each afternoon. Before then we 
will fill the air with hundreds of 9- and 1-2- 
foot Aeroplane Kites oft-very known kind. 
By flying these, dozens in tandem, 
enormou.s American flags, streamers and 
announcement banners about thi- meet can 
be lifted a half mile in the air. 

C These .scientific kites will fly 

all day and the displays will be 

a great attraction in themselves 

and will keep the crowds quiet 

and contented, when for any 

reason the aeroplanes cannot fly. 

C At the Meet of the West Hudson Aero 

Club at Arlington, X. J., June, 1909, New 

York papers said, "The hundreds of kites 

in the air were a decided feature."

noto show conclusively that the principle of opera- 
tion of this new U. & H. Master Magneto is cor- 
rect, and that while it is possible to secure fairly 
satisfactory results by connectin.s; two separate 
nias-iietos to the motor, the use of the U. & H. 
ra<'inK magneto assures the maximum efficiency of 
(hi' motor at all times, owing to the fact that it 
is impossible for the sparks in any cylinder to 
occur out of synchronism. 

Aside from the principal features outlined above, 
the magneto is of the well-known U. & H. con- 
struction, employing the U. & H. non-adjustable 
iutirrupter, which is another detail of great in- 
iincst to racing men, as it eliminates all possible 
chance of ignition difficulties, due to breaking or 
sticking of the pivots, springs, insulation, and 
other parts used on other types of interrupters. 
The armature and distributor of the machine are 
mounted on annular ball bearings, which effectu- 
ally eliminates any possibility of trouble, due to 
lack of oil. 

Buffalo Pitts Co. Building Aeroplane. 

The Buffalo Pitts Company of Buffalo, N. Y., 
who are large engine build'ers, have under con- 
struction an aeroplane. In the course of their 
experiments with this machine over a number of 
years, they had occasion to try out certain models 
demonstrating new aerodynamic principles, and one 
(if these models created so much interest in its 
operation, that they decided to make a flying toy 
novelty of it, which they have done, giving it the 
nanii' of "Hi-Flyer" helicoptic flying rnachine, pat- 
ented and copyrighted. 

This little machine flies to a height of over 
GOO feet, and can be operated by any child. Shoot- 
ing the "Hi-Plyer" is as much fun for grown 
people as for children, and is an excuse for out- 
door exercise for everybody. It has been the sen- 
siation of the aviation meets throughout the coun- 
try. It is used by aviators for determining the 
direction and velocity of the wind at high alti- 
tudes, and there is a special demand for it for 
this purpose at aero clubs, as well as for use on 
golf courses, and at amusement parks and beaches. 

Kites Now Feature of Meets. 

The kites of Samuel P. Perkins were a con- 
tinual source of amusement and interest during 
the Indianapolis. Montreal and Toronto meets. 
These flew all the time and provided the public 
with something to look at when the 'planes did 
not fly. One Montreal newspaper featured an an- 
nouncement of the kites on its news bulletins, 
illustrating the surprising value kites are lending 
to meets. These kites are sent up on many 
lines, singly, in tandem and other ways, and carry 
various banners, streamers and flags, advertising 
either the meet or articles of general use. If 
there is not enough wind for kites small balloons 
take the place of the kites and perform the same 
usefulness. The regular outfit numbers 100 kites 
of all kinds. A nW stunt is a huge box kite 
made like an aeroplane, with rudders and pro- 
peller. In the air it looks exactly like the real 
thing and remains statiomary in the air. In this it 
has it over its original. 

Rinek Aero Mfg. Co. 

The Rinek .\ero Manufacturing Company of 
Easton. Pa., was recently incorporated with C. 
Xorvin Rinek president and Frank Buckman, sec- 
retary-treasurer to conduct the light motor and 
aeroplane business heretofore handled by the ma- 
chine department of the Easton Cordage Com- 
pany. It was felt that on account of the rapidly 
increasing business handled by the machine de- 
partment that a greater volume could be more 
efflcientlv handled by an organization devoted 
solely to' aeronautics. The Rinek engine has found 
favor through consistent performance and good 
workmanship and material. Philip W. Wilcox, 
who has built a Farman-type machine at Mineola, 
speaks highly of the motor and the company's 
treatment of him.

About Hartford Tires. 

While to many people it may seem strange that 

flying machine is eipiipped with tires, never- 
leless in almost all cases this is true. The 
urtiss machine used by Charles K. Hamilton in 
is flight in New Britain is fitted with three 
fartford aviator tires 2() in. by 2 in. in size. 

Hartford tires have been used since the fii-st 
lays of the bicycle, and have kept abreast of the 
roeession of new inventions, and when the 
eiiJiilane became po'nilar and tires were found a 
■qnisite part of their equipment, the Hartford 
iihiier Co. had three styles of tires to offer. At 
!'■ first aerial sliov*' lield in jNIadison Square 
allien the Hartford company was the only tire 
vhiiiitor. shovvin;: at that time its aviator, aero- 
lane and aeronaut tires. 

I'liese tires are pneumatics, mostly in small 
/es and of special construction to afford all the 

siliency possible, as this is necessary to aid the 

a.iiine in starting from the ground — and yet the 

hi must be very durable and of a certain 

-Me of tou'jhness to withstand contact with 
ivi.icies wliicli may cume in thi> path of the 

rn|ilane. 

■|'lien> are already in this country more than a 
iinili-ed flying machines fitted with Hartford tires. 
eeintly a good-sized shipment was made to the 
urtiss factory.

They report a largo demand for their laminated 
ribs, which are carried in stocli and made to 
order, the four-ply .Ti-ft.. ."i-ft. (>-in. and G-ft. 6-in. 
lengths being favorites. 'I'hey are now filling an 
order for ribs of tlie exceptional size of 8 ft. (i in. 

The 20-in. aero wheel made by this company is 
replacing a number that have "dished" its 7-in. 
hub, steel rims and heavy spokes, making it jirac- 
tica.Uy unbreakable. Regidarly ecjuipped with ball 
bearings. Friction bearings on order. 

They .are now placing on the market a knock- 
down plane, or rather a biplane, carrying surfaces 
30 ft. by 5% ft. The outfit includes laminated 
main beams and ribs, struts, sockets, joints and 
rib connections, to which can l>e attached any sort 
of rudders and chassis, one of the three types 
made by this company, or by the buyer. 

Mr. Cleve T. Shaffer, whose technical desi-rintion.s

Elbridge Engines Improve. 

Mr. A. P. Warner of Beloit, Wis., the lirst ama- 
teur to fly in this country with a Curtiss machine, 
lias announced' his intention of building a new ma- 
chine after ideas of his own during this summer. 
He expects to equip it with an Elbridge ■"feather- 
weight" engine. 

^'ery rapid advancement is being made in the 
design and construction of the Elbridge "feather- 
weight" engines. Fundamentally the engines re- 
main the same, but drop forged steel connecting 
rods, new pistons and a more efficient system of 
manifolds have improved the engines in both ap- 
pearance and efficiency. The engines now being 
turned out at the rate of one each day are said to 
deliver 15 to 20 per cent, more tlian rated power. 
Regular deliveries are now being made in 1(> days 
after receipt of orders.

Harmon Uses Pennsylvania Tires. 

One of the Herreshoff brothers is building an 
aeroplane and is equipping it with the large di- 
ameter Pennsylvania 'aeroplane tires. The Penn- 
sylvania Rubber Co. has supplied Clifford B. Har- 
mon with rubber to renew the shock absorbers on 
his Farman. which is already equipped with Penn- 
sylvania tires. 

The Pennsylvania Rubber Co., whose works and 
main ofHce are located at .Teannette. Pa., and who 
are now giving emuloyment to nearly 1.000- peo- 
ple, have recently put on the market an aeroplane 
tire i>eculiarly suitable to the advanced stage of 
aeroiilane dr'veloi)ment. 

IIi>ret()fore molorcvcle tires of L'V^ in. and ." in. 
section have been largely used on aeroplanes. 
Such tires are not designed or adapted to stand 
the shocks of alighting and have little cushion- 
ing effect. It is therefore often necessary to use 
four wheels on an aeroplane, resulting in a con- 
siderable increase in weight and air resistance; 

The Petinsylvania aeroplane tire is 20 by 4 in. 
in size and is of light but strong construction. 
Two of these tires will carry a ten or twelve 
hundred i)Ound flyer, and will have sufBcient cush- 
ioning effect to prevent the jar of alighting being 
transmitted to its delicate framework. 

This tire is similar to the Pennsylvania clincher 
automobile tire, but constructed with a view to 
its use on aeroplanes. 

The 20 in. by 4 in. tire complete with tube 
weighs onlv seven pounds. For lighter machines 
thev are turning out a 2Vi-in. tire in both 2r>-in. 
and 28-in. diameter of the same light and strong 
construction which may be employed where the 
use of a wheel of a larger diameter seems to be 
advisable.

Requa-Gibson Propeller Holds Record. 

Clifford B. Haiiiiou, who holds the United States 
amateur endurance record with his Farman, re- 
cently had the machine fitted with a Kecjua-Gibson 
reguhir type propeller, 81/2 ft. diameter by 2-ft. 
pitch. Referring to its performance, Mr. Harmon 
writes : "With this propeller I broke the amateur 
record of America of 1 hour 5 minutes. It seems 
to be giving entire satisfaction." 

With this propeller and the engine rumiing at 
1,200 r. p. m., the pitch speed figures 2,400 ft. 
per minute. Now, the aeroplane flies at 40 miles 
per hour, or .3.520 ft. per minute, which is con- 
siderably more than the pitch speed of the pro- 
peller. Patrick Y. Alexander experimented with 
model propellers on a wire on board the steamer 
traveling between England and America, and found 
that these advanced into the wind. The Kequa- 
(iibson company promises some startling informa- 
tion in the near future, as the result of present 
investigations.

The Lincoln Aero Club is the name of a new 
body just organized for the purpose of discussing 
atrial navigation and promoting the sport in Lin- 
coln, Neb. The six charter members are Dr. (J. R. 
P.rownfleld, Joe Burnham, Commandant H. E. 
■iates of the University cadet battalion, G. W. 
Chowins, superintendent of grounds and buildings 
at the university ; E. C. Babcock. and Dean Rich- 
ards of the department of engineering at the uni- 
versity. As soon as possible club grounds are to 
l>i' established somewhere on the outskirts of the 
city where the necessary sheds and other equip- 
ment will be erected, and test flights will be made. 

Dr. Brownfield is working on a 4-ft. model for a 
double biplane on which he has applied for a 
patent. He is to have two pairs of planes, one 
l>air directly ahead of the other. His machine, 
according to the model, he lias constructed, is to 
have at least two advantages over the Curtiss 
and Wright machines. Both of these operate in 
preserving the equilibrium of the machine. One 
is a controller operated by the engine and the 
other is a pair of wings lying on a horizontal 
plane on either side of the machine. These are 
operated by means of a lever. If the machine 
should dip to the left, for examjjle. the left wing 
being thrown out to offer resistance in the atmos- 
phere, while the right wing is raised to relieve 
resistance. 

Dr. Brownfield, of 1234 "O" St., is enthusiastic 
and has arranged for the club to visit the Omaha 
meet in a body.

STARTING DEVICE FOR SALE. 

D. D. Wells, R. F. D. 2, Jacksonville, Fla., has 
recently taken out a patent covering a skid to 
assist starting on rough ground without employing 
any track. 

in the sketch, Pig. 1 is a side view, Fig. 2 shows 
a transverse section of same, Fig. 3 is a detailed 
ind view of one of the pulleys with the belt 
.'ipplied thereto and Fig. 4 is a detail sidle elevation 
of one extremity of the skid. 

In operation the skid is positioned on the ground 
u lien the outer face of the lielt (11) engages with 
tlic ground and the runner (10) is supported upon 
the upper lubricated face of the belt. When the 
skid is forced longitudinally, the runner is caused 
to slide over the belt and to cause tlie movement 
of the belt beneath the runner and over tlie pul- 
leys (l.">). The guides (16) engage the beads (15) 




throughout the length of the runner, and holds 
I 111' lielt in concaved position to en;;age aliout the 
polislied surface of the runner. As the belt reaches 
the end of the runner at the rear extremity of 
llie skid, the same is released from the guide (lt)t 
and permitted to engage over the flattened surface 
of the adjacent pulley. Mr. Wells desires to dis- 
pf)se of the patent at a reasonable figure, as he is 
financially unable to exploit it.

CENTER OF PRESSURE. 

(.Question : Please inform me how to find the 
center of pressure on a biplane whose surfaces 
measure 5 ft. fore and aft. with a curve of 1 :20. 
The angle of inclination is 6 degrees when the 
aeroplane is on the ground. Must not the center 
of gravity be just a little below and back of the 
assumed c. of" p. wlien the aeroplane is not in 
motion, considering that because in flight the 



70 



AERONAUTICS 



August, igio 



c. of p. moves forward, the center of gravity must 
be rather in front of the assumed c. of p. ? 

Answer : One can suggest no convenient way to 
And c. of p. of an aeroplane except by actual trial. 
The c. of p. of a small experimental plane having 
same depth of curvature would bo for 6 degrees 
about 44 per cent from front edge, and if this 
hold true for a large surface it would be 2 ft. 2 in. 
from front : that is, for a circular arc. For a 
parabolic curve it would probably be further for- 
ward See discussion, of Aerial Experiment As- 
sociation in June, 1909, number, pp. 175-7. The 
weight, or center of gravity, should in general be 
forward of the c. of p. This point depends some- 
what on the method of vertical control (the dih>- 
position of elevator and horizontal ruddfr). See 
also p. l.")."}. April, 1910, Aer(1n.\utics, and article 
by M. 15. Sellers, pp. 77-79, March, 1910. 

HOW TO MAINTAIN CAMBER. 

One n:<'thod of maintaining the camber of ribs, 
though not generally used, is to use a thin span 
wire to .join the tips, this wire forming the chord 
of tho rib. Ribs are usually bent after steamin,g, 
dried and then made impervious to moisture by 
varnish. .\s long as they do not absorb moisture 
they will stay bent. 

Laminated ribs can be glued and bont at onco 
while the glue is wet, put thus in a form to dry 
and when dry taken out and varnished. These 
will hold their shape, even though they absorb 
some moisture, providing the glue docs not soften. 







-f^re'.r ^/*At 



How to Make Rlls 



Another method of making riba is as follows : 
Take thin boards of the desired thickness and wood 
and glue them together, one on top of another. 
While tho glue is wet place tho laminated board 
thus made into a press or form tho shape of tho 
ribs you want. Clamp the form tightly together 
and placi' the whole in a drying oven for several 
hours. When dry the ribs can be sawed out of this 
curved board. A correspondent says that if ribs 
are wet or soaked, then bent on a board and help 
by bent nails, then dried and burnt a little by a 
gasoline torch on the concave side, they will 
say bent. 

THE WILLOUGHBY .STEERING DEVICE. 

Dear Sir : 

I was invited by Mr. Harmon recently to wit- 
ness a flight in his "Farman" machine, lately 
purchased from Paulhan, who used it at Los .\n- 
gi'los last winter. I was quite suri)risod to find 
that it steered in the vertical plane with my 
patent steering device (applied for on the IGth of 
.Tune, 1909, several of the claims having already 
l>ren allowed I. 

This patent consists in steering an aeronautical 
machine in the vertical and horizontal planes by 
a oonibination of rudders. All biplanes stoor uj) 
and down by tho head alone. All monoplanes 
steer up and down by the tail alone. In my device 
th(> "War Hawk" steers up and down by both head 
and tail at the same time.

PADDLE WHEEL DEVICE. 

Dear Sir: 

Dr. (Jreene of Rochester, who is building an aero- 
plane, kindly refers me to you for address of 
parties interested in the idea of a folding slat 
paddle wheel, which device, he says, has been 
patented, for sustaining aerial machines. I think 
I have a method of appreciably increasing atmos- 
pberical r(>sistance to downward movement of a 
paddle or wing and thereby increasing its lifting 
effect, and would like to get in communication 
with parties desiring to have such a device made 
more effective than it has so far proved to be.

to Conyers Graham in

IN ' DISPUTE 

The aeronautical controversy still con- 
tinues. Dr. Thomas Edwin Eldridg-e sent 
the following letter to The North Ameri 
can yesterday, taking polite exception to I \ 
some statements made by Conyers Gra- | t 
ham in yesterday's issue: 

"Apropos of the article in this morn- 
ing's issue of your paper," he says, "I 
regret to say that Mr. Graham is again 
misinformed. Heretofore, Dr. T. C. Fulton, 
president of the Ben Franklin Aeronauti- 
cal Association, has always claimed the 
record for altitude, distance amd time in 
the air for the Ben Franklin. The Phila- 
delphia Aeronautical Recreation Society, 
I therefore, must continue to claim for its 
j balloon Philadelphia II the amateur rec- j 
ord for altitude and distance from Phila- 
delphia, this being proven by the recor(Js. 
"Incidentally, commenting upon Mr. 
Graham's statement, please let it be un- 
derstood that the only balloon ever used 
in Philadelphia for advertising purposes 
is the Ben Franklin, inasmuch as on its 
first ascension there were dlstributeid free 
beer checks, advertising a local brewery 
and the president of the association was 
with the party on this ascension. May I 
add further that the bylaws of tlie 
Philadelphia Aeronautical Recreation So- 
ciety do not permit its air craft to be 
used for advertising purposes, nor do the 
rules of the society allow Its passengers q 
or guests to carry intoxicating liquors." .. 






BALLOONIST 



Philadelphia II Has Amateur 

Long-Distance Record, Says 

T. E. Eldridge 



QUESTIONS STATEMENT 



In the controversy over rival claims to 
records between the Philadelphia Aero- 
nautical Recreation Society and the Ben 
Franklin Aeronautical Association, Thom- 
as Edwin Eldridge, of the former or- 
ganization, yesterday sent out a letter 
disputing a statement regarding a trip 
made by Conyers B. Graham, of the Ben 
Franklin association, in 1907. The letter 
says: 

"The Philadelphia Aeronautical Recrea- 
tion Society concedes to the Ben Frank- 
lin Aeronautical Association the record 
for time in the air claimed by Dr. T. C. 
Fulton for the balloon Ben Franklin on 
October 17, 1907, by twenty-five minutes. 

"The Philadelphia Aeronautical Recrea- 
tion Society, however, does not concede 
the record claimed by Conyers B. Graham 
for the balloon Ben Franklin on its trip 
to Dwight, Mass., and the statements 
made by Mr. Graham concerning this 
trip are not correct. 

"The balloon Ben Franklin never sailed 
from Philadelphia to Massachusetts, but 
did sail from Aura, N. J., to Dwight, 
Mass., in 1907. This ascension was made 
on Saturday afternoon about 2.30 and 
landed at Aura, N. J., about 5.20. On this 
short trip were Prof. Samuel A. King, a 
professional pilot, with Dr. George H. 
Simmerman (then vice president of the 
Ben Franklin Aeronautical Association), 
Edward G. Rech (then its secretary), 
Henry Gratz, Mr. Longacre, George 
Mayer and Dr. Thomas Edwin Eldridge. 
From Aura, N. J., the following day, at 
1.05 A. M., the Ben Franklin started again 
and from this point landed in Dwight, 
Mass., about 9.20 A. M., Professor King 
being the pilot, while the gerttlemen in 
the basket were Dr. George H. Simmer- 
man, Messrs. Kech and Mayer and Dr. 
Thomas Edwin Eldridge. Neither Mr. 
Grat7. nor Mr. Longacre were in the 
basket when it sailed to Dwight, Mass., 
as claimed by Mr. Graham, and as the 
records of the Ben Franklin Aeronautical 
Association will corroborate. 

"The amateur balloon record for alti- 
tude, 17,050 feet, made by Dr. Thomas 
Edwin Eldridge, Dr. George H. Simmer- 
man and "Welsh Strawbridge, on June 
10, 1910, and the distance record of 250 
miles, air line made last week from 
Philadelphia to Pascoag, R. I., by Dr. 
Thomas Edwin Eldridge, William S. 
Underbill and Arthur S. Underbill, are 
unquestionably held by the balloon Phila-

WE are forced to print all new material this 
monith in, small type in order to make 
room. There is on hand considerable 
amount of material in type for wliich we have 
been unable to find space as yet. 

Hour flights abroad are so common that it 
seems useless to further chronicle them, and in 
the future we will merely try to print new rec- 
ords made, new machines, especially long flights 
and events of more than usual importance. 

PRO(iRE'SS will certainly demand its toll of 
lives, but there is certainly no cause for 
alarm. Fatalities have not been as numer- 
ous as those which occur in nearly every auto- 
mobile meet of importance, and the entry list in 
the aviation meets has been fully as large as that 
of any motor race. Considering the number of 
flights made, both at meets and elsewhere, the 
restricted grounds at which many meets are held, 
one may feel assured that the percentage of fatali- 
ties is small. 

A word of caution is necessary, however. De- 
velopment does not appear to be along the line 
of making safer machines, but in building faster 
and more varied' types. Familiarity breeds con- 
tempt, and aviators should not take the fearful 
chances that some do. 

IT is worthy of comment that aviation, abroad 
has reached the stage where meetings may be 
held on the same basis as motor and horse 
racing, where competitors pay entrance fees re- 
turnable only on condition, say, three laps of the 
course are made, and where the sole remunera- 
tion consists in the jirizes to be won. 

Correction. 

In the article, "How to Make a Propeller,'" in 
the .July number, the last two paragraphs, by mis- 
take, were misplaced and put in the adjoining 
column. The last sentence of the article should 
read : "This will NOT duplicate, however, a Cur- 
tiss propeller, etc." The word "not" was omitted.

What Bishop Says. 

" 'Will the Wrights compete for the International 
Cup?' 

" 'No one knows as yet ; they refused! last 
year to compete and it is I, Cortland Bishop, 
who paid the expenses of Curtiss so that one 
American aviator might compete for the cup and 
he won.' He adds with a practical and national 
instinct; 'it cost me a great deal of money.' 

" "It has been said that the International Cup 
would cost aviators very dearly in expenses, etc., 
and would only result in the winning of an art 
object of medium value.' 

" 'No doubt, but French aviators are free to 
come or not as they please.' 

" 'Then your opinion is that apparatus of French 
origin will win over the American's?' 

'• "I have not ridden with the Wrights but only 
with Paulhan. The impression of security is 
perfect andi must be much greater than with the 
Wrights. These oscillate a great deal in the air 
and I believe in the superiority of the French.' 

"Mr. Cortland Bishop stopped and offered ami- 
ably to complete the interview when dcsiriMl. 
We shook hands cordially and transatlantically 
and he renewed his walk towards the Tuileries." 

The above statement of Bishop with respect to Cm ti'^s 
is not an accurate statement of the facts. 

The labove interesting item was printed in the 
French organ I'Aero. being an interview with the 
honored president of the Aero Club of .A.m€rica.

BALDWIN'S VULCANIZED PROOF MATERIAL 

Used in the U. S. Gov. Dirigible and Spherical Balloons 

WILL last from five to six times as long as a varnished balloon. The weight 
is always the same, as it does not require further treatment. Heat and cold 
have no effect on it, and ascensions can be made as well at zero weather as in 
the summer time. The chemical action of oxygen has not the same detrimental 
effect on it as it has on a varnished material. Silk double-walled VULCANIZED 
PROOF MATERIAL has ten times the strength of varnished material. A man 
can take care of his PROOF balloon, as it requires little or no care, and is NOT subject 
to spontaneous combustion. Breaking strain 100 lbs. per inch width. Very elastic. 
Any weight, width, or color. Will not crack. Waterproof. No talcum powder. No 
revarnishing. The coming balloon material, and which through its superior qualities, 
and being an absolute gas holder is bound to take the place of varnished material. 
The man that wants to have the up-to-date balloon, must use VULCANIZED PROOF 
MATERIAL. Specified by the U. S. SIGNAL CORPS.

1 he Call Aviation Lngine 



IS 



1st. .4 Four Cycle Engine. Tlie type used on 90% of all automobiles and motorcyles. The 
type used by all prominent aviators here and abroad, and holding all aviation records. 

'ind. A Water Cooled Engine. The only kind that can be dependfd upon for extended runs 
without danger of overheating. Our spiral water jacket, together with piston pump circulation is 
the most perfect cooling sys em yet devised. 

3rd. An Oppofscd Culinder Engine. The construction conceded by gas engine authorities to 
be the nearest vibration less iy\ie. By all odds the construction best adapted for aviation purposes. 

4th. A Silent Engine. The only engine yet designed for aviation liaving both main and 
auxiliary ports silenced. Hence the only aviation engine adapted for permanent use, or for other 
than merely exhiV)ition purposes. 

r)th. .-t "Fool-Proof" Engine. The utmost simplicity of construction, small number of 
cylinders, together with its being of the usual Four Cycle type, enables any automobile chanftVur to 
set and run it. not one in fifty of whom have any experience with Two Cycle, Revolving Cylinder, 
or V^-sliaped multiple cylinder engines. 

fith. A Tliorourihli/ Dependable Engine. Our Magnalium outer casing for cylinders and 
cvliiider he ids permits of a remarkably strong construction with minimum weight ; while our Vana- 
dium Grey Iron Cylind'-r and cylinder head linings, piston heads, valve cages, valve seats, etc., is the 
only dependable mitcri il for these parts. 

7th. A Superbly Beautiful Engine. The entire de-sign is thoroughly artistic; while all ex- 
posetl parts not constructed of Magnalium -a shining non-corrodible metal — are nickel plated, the 
whole surface l)eing polislied to a mirror finish. 

8th. Phenomenally Pou-erful Engine. This result is .secured by the u.se of a comparatively 
small number of cylinders of generous proijortions, as distinguished from a multiplicity of cylinders 
with their numerous be irings. and consequent friction, and liability to derangement. 

9th. An E.fceptionidly Economical Engine. It is a matter of common notoriety among gis 
engineers that economy of fuel, as compared with power developed, is secured by large cylinde:s, 
few in number, rather than by a multiplicity of small cylinders— a consideration of paramount im- 
portance in aviation. 

lOth. ^-1 Moderate Priced Engine. While the material and workmanship of this engine is even 
superior to the very expensive foreign makes, and not to be classed with the cheap engines flooding 
the market, yet our aim has been to furnish avi iters with a moderate priced engine, cheaper th;in 
could be produced by themselves, except in large numbers, and with an expensive shop and foundry 
equipment.

Gentlemen: 

I wish to let you know that the 
oil which befouled ray spark plugs was not 
your oil. I used KOBILOIL going to Phlla- 
dolphla and had no trouble. Owing to mis- 
understanding, I was suppliaiJ there with 
some other oil, which caused the trouble 
resulting in my descent. Had I used Mo-

ftif/ht. The imiier i-oiitiiiiis much food for 
i/ht. — Till-; KniToi!. 

OH a numUcr of ycjirs I have ixitcd the need 
of some i-i'liable method of di'teriuiuiuft 
the horse jjowei- of small internal eom- 
bustion and other portable engines, and 

ite tie piissible vahie of some device which 

I be attached to aeronautic and other similar 
les to show at all times the horse power 
ioped by the engine while in actual service. 

steam engineer can tell by a glance at his 
n gauge whether his pressure is high or low 
knows at once if he is supplying his engine 
the maximum pressure. The gas engineer 
Snot this aid. but must trust blindly to olttain- 
( he right c<)nil)inati(>ns of numerous conditions 
S then guess at the result. ***** 
'ere are various methods by which this may 
one. of whicli I mention three, besides the 
i I will describe later : and of which last- 
sioned method I believe 1 am the origin- 

! ould my method prove of vaUu'. I will exact 
( ondition that the same be called as I have 
itened it, ■'The Reaction Test." to deter- 
; the iKirsejiower of engines and other ma- 
i's where aiiplical)le : and further, that the 
\ !• lie accredited to me unless someone else 
I ir(i\e a better and prior claim. 

' lirst of the three methods mentioned. I 

i-^i.iic. is the well-known 'Trony brake lest." 

1 I viiu will later note that I seem to follow 

■I way. l)ut a close analysis will show a 

'il (lei)nrtur(> in some respects. 

' siccind method in merit I will accord to 

■'1\ naniometer." also well known among (>ngi- 

lUii' aitplication of which is to attach a 

ini lilades to the shaft of the engine, said 

- iiiing of a known area and set at a 
■ ill distance from the shaft centers, at a 

■vpccd <'xert a certain amount of resistance. 
■iliiiLi to area, diameter, speed »nd atmositheric 
ii.\ From these we may calculate constants 

iwi'd in conjunction with speed of engine. 
I ■ next method is an electric one or the 

II resistance of electric currents flowing 
• ^li i>roper conductors, or magnetic effects. 

b sr three methods are all of merit in certain 
-. liut none of them can be utilized, as far 
'■ writer knows, while the engine is develop- 
;isi'fnl work, ])ossibly excepting some of the 
<ii- devices, 1 will endeavor to show how 
,M device may be applied to aeronautical and 
1 'Ugines showing at all times the exact 
'r ixerted l)y the engine without absorbing 
ill ibe energy develoijed by th(> engine while 
'lull service. Said device. I think, need 
\ i-ili more than l(i pounds for a ."iu- horse- 
[1 I ngine. and may be applied equally well to 
.).iil\ing cylinder type or th(> ordinary crank 
I type. With the aid of another attachment 
4I11 weight the exact pull or thrust of pro- 
may be measured at th<' same time in a 
nr manner. This may lie useful to aid in 
milling the variations due to changes in at- 
li. !i<- condition and also in ditTerent alti- 
I .1^ well as showing at once ihe best mean 

- ^iieed, junver absorbed and pull of proi>eller 
'luying conditions, absolutely doing away 

-m sswork. With the aid of a^suitable speed 



indicator and a graduated strip or ribband of 
paper i)a.ssing over a small, light drum driven 
by suitable means from engine shaft, it will be 
))()ssible to obtain an accurate record under varV- 
ing atmospheric conditions. 

Now in describing my method I will follow 
for a way the "Prony brake" system, the same 
rules for calculating being used :' but the method 
of proci'dure being diametrically opposite, theiv 
being no braking elt'ect in my method and posi- 
tively no absorption of power as in the other 
methods. I measure the [lower from the end of a 
lever ijractically in the same manner as may be 
done on the Prony system, but on the opjiosite 
side and contrary-wise direction or in reverse 
direction of transmitted power. 

.\ssuming a horse jxiwer to equal :;;!,(i(i<i pounds 
raised one foot high i)er minute, a pulley '.V.i ft. 
in circumference rotating l.ddOi r. p, m. would, 
with a resistance of one pound at the periphery, 
be exerting one horse power: with a l(»-pound 
resistance. 10 horse power: '>(} i)ounds resistance 
our load e(iuals ."io horse power. If the ijullev is 
rotating .'(K* r. jj, m. then our indicated horse- 
jiovver eipials one-half of the above stated amounts. 
If speed of pulley should be 2,000 r. p, m, then 
our reading would be doubled or 2, ijd and 100 
horse power, respectively. This pulley, like the 
North Pole, does not exist, so all persons are 
warned not to fit out any exj)editions to search 
for it. but is used only as an illustrative point.

But we do ui'Vcitheless utilize a lever in the 
place of the pulley and for convenience sake in 
computation consider it to e(|ual one-half the 
diameter of the jiulley, altlKuigh it may be in 
practice jireferably shorter and also on that ac- 
coimt comi)ounde(l to reduce weight and pressure 
on the same principle as the platform scale, or a 
lever of the second order, therefore, ."!.■) ft. circum-

corresponding sjieeds. 

.Now I>iagram .\o. 1 will show the application 
of the Prony lirake iiriuelple. Let .\ be the

means to tighten the pressure on pulley, E the 
flow of water to prevent the ignition of wooden 
blocks and overheating of pulleys by friction. F 
the platform scale on which the thrust of lever 
is weighed. This thrust is in the same direction 
as the engine shaft and engine must be bolted 
down or otherwise well secured to prevent over- 
turning. A speed indicator being used in con.iunc- 
tion with the apparatus as in the dynamometer 
method and a constant to assist in the com- 
putations. 

Now as the method is generally well under- 
stood and may be readily observed from the dia- 
gram, it mav not be necessary for me to go 
into further " details of the Prony brake pria- 
ciple, therefore in Diagram No. 2 I will illus- 
trate my method of "Reaction Test." 

Let A represent the engine, B the support for 
engine which may include a ballbearing and 
slipped on engine shaft, but preferably a short, 
proiecting part of hub supporting engine shaft 
bearing. At each end of crank case and con- 
centric with shaft, permitting a free movement 
of the entire engine and crank case independent 
of crank shaft movement, through a small arc 
of possibly 5 deg. will be sufiicient. 

Connections to engine, such as water circula- 
tion and supply pipe must be made flexible, of 
course, to permit free movement of entire engine 
tbrousb the small arc needed. Should euTin'^

above mentioned; my theory being that the foi 
exerted on the crank shaft is also equall 
by an opposed force from the crank case 
those types where crank shaft revolves and 1 
reverse' order in the revolving;' cylinder ty 
In the latter case we would merely attach ( 
lever to one end of the crank shaft and in t 
event allow free movement as before stated. 
only remains now to attach another small le' 
and dial to the thrust bearing of propeller 
determine the pull of same and a small spi 
indicator attached to engine to comjilete c 
equipment. The power dial will now show i 
torque exerted, the speed indicator the r. ]). 
of engine and tlie propeller dial the pull 
pounds. If we do not wish to add extra nicch; 
ism to compute our indicated horse power 
may do it easily mentally. For instance, sjk 
indicator shows 500 r. p. m.. power dial 40 pouu 
we are securing 20 horse power. The propel 
dial speaks for itself and if propeller is prope 
designed should show a pull of not less than 
pounds per horse power developed, or in t 
instance 180 pounds. 

Should our speed dial register 1,000 r. p. 
then our reading with the same pressure 
power dial would be 40 horse power and i 
I'loieli'T should shew oGO pounds pull. In 
favorable atmospheric conditions and engine

be of a design which is top heavy ; that is, the 
center of gravity very much above the crank 
shaft, then we would probably have to counter- 
liMlance by attaching underneath the engine crank 
case, radiator or some other part of the equip 
ment ; or it is permissible to make our engine 
supports large enough and eccentric to shaft to 
obtain center of gravity : in which event a flexible 
or universal .ioint would have to be provided 
for propeller shaft. Tills overbalance might not 
effect reading but a very small per cent while 
on an even keel, but doubtless would if a violent 
rocking motion were given to plane or wherever 
I lie appliance were used, but as it is intended 
solely tor aeronautical work, we will not further 
consider outside effects. 

In the type of engine which I am now develop- 
ing and have patents pending, the cylinders are 
diametrically opposed in pairs and the center of 
gravity lies nearly on the crank shaft, therefore 
thc.v normally assume a horizontal position. Let 
(' represent our lever which we will compound 
on to the indicator hand to reduce weight and 
))ovver of calibrated spring required. C being 
liolted fast to crank case moves through the same 
.•u'c of vibration. D represents registering dial 
on which are indicated the pressure of the lever 
in pounds, corresponding to the 10-ft. pulley first 
mentioned. It may be noted here that the thrust 
of crank case lever C is in the opposite direction

dial will indicate by the pointer If the en; 
does not keep up the pressure, whether <Uu' 
lack of fuel, or air, or other cause, as any ex 
friction due to sticking pistons or hot journ

very light and thin, then the speed dial n 
show the engine is turning over all right, 
with a corresponding reduced torque and a fall

at a glance what is wrong. A wind anomome 
may assist in securing positive data on wli 
to "obtain more accurate calculation as to ca 
and effect of various altitudes and changes of 
mosphere in the operation of aeroplanes and ot 
kindred subjects. 

By utilizing the three indicators as previou 
mentioned, we may further make note of ot 
phenomena which will be of value to the avia 
and scientist alike. We can measure in act 
service the variations in propeller thrust duo

To avoid tyix' description in connection with 
"Constnu-tion Aids" has been the aim all 
along, making the sketches themselves fully 
explanatory- 
Fig-. 6 illustrates an interesting article by Marc 
Paird in our English contemporary AcioiKiiitics. 
He says : 

"The carrying surfaces of a monoplane enter 
into two classifications : the rigid and the flexible. 
The former type, which forms the rational solu- 
tion of a light framework. i.s so expensive and 
so fragile that it has not been generally adopted. 
The latter type, on the other hand, has now 
been made to acquire a sufficient degree of rigid- 
ity. 

"Instead of merely nailing down the cross 
ribs at their intersection with the main and 
secondary transverse spars of the vving. the joint 
at these points is now stiffened by various bind- 
ings, small blocks of cork glued in the corners, 
and other similar devices. Small square strips 
of Irish linen, even, glued in every corner have 
Ijroved to strengthen the Bleriot type of wing to 
a material degree. The saw-cuts made in the 
distance pieces of the ribs, by the use of a 
band-saw (instead of a fret-saw) have to be 
closed l)y some process of this kind. (A) 

"The general arrangement of the framework 
of a large wing, measuring some 20 ft. span 
from root to tip. Is .shown in ( P. ) . Strips of 
wood, preferably spruce. 1 in. wide, are used for 
the cross ribs. These taper down at either end. 
since the greatest strain nearly always falls 
about the center of their length (C). The dis- 
tance pieces are carved out of willow % in. 
thick (D). They are fixed to the ribs by means 
of linen tape bound three or four times round 
and glued down. 

"The built-uj) transvers(> Itearas are made of 
two ash boards, i/^ in. thick and 2 in. wide. 
.V small number of distance jiieces are sufficient 
to keep the boards together, since the ribs are 
placed only 1 ft. apart. In fact, three distance 
pieces for each beams are ample ; two are utilized 
for fastening the steel bands to the wings, as 
shown in (Ei, and one to strengthen the root. 

"The construction of the fuselage of a mono- 
plane has given rise to innumeralile experiments, 
designed to produce a structure combining ex- 
treme lightness with very great strength. As a 
matter of fact, one may state without exaggera- 
tion that those structures that present the ajjpear- 
ance of greatest finish and neatest workmanship 
are generally the heaviest and most liable to 
break. Heavy, if aluminum sockets ar(> employed ; 
l)reakable. if any holes are bored in the beams. 
These members of the fuselage should never be 
pierced or weakened. They require a tight bind- 
ing on their whole length, or at least in the 
vicinity of the struts. In this connection I may 
mention a useful tip, which is illustrated in F 
and (J, and which has been found very successful 
in practice." 

A valuable feature has been added to the aero- 
nautic department of tlie Philadelphia Inqiiirer'x 
Sunday issue, consisting of a weekly article by an 
expert, who writes under the name of Rirdman. 
These articles are written in a briglit, conversa- 
tional style, and are replete with interesting facts 
and gossipy discussion of timely aeronautic mat- 
ters. The Inquirer inaugurated a regular aero- 
nautic department more than two years ago, at a 
time when many other newspapers were printing 
facetious articles about "present-day Darius 
Greens," belittling the ett'orts of aviators wlioiii 
they now laud to the skies. Tlie chief cliarac- 
teristic of tliis paper's aeronautic department is 
its sane editing. It wastes no .space on fanciful 
schemes with absurd illustrations, but is a leader 
in the publication of real news and authoritative 
articles on aeronautic subjects. 



The returns from the Louisville "meet" on .Tune 
18-1'J are of interest to show the results under 
proper management. 

The sum total taken in was $03,036 in two 
days. The affair cost about .$11,000. leaving a 
profit of $22,636. Had Curtiss been able to fly 
an hour earlier on one of the days, it would have 
meant a <-i(nsi(lerabl(> increase.

J. Prentice, Captain, U. S. A., stationed at 
Fort Hancock, X. J., has been working for a con- 
siderable period on the structure and curvature 
of the gull's wing, building many models and a 
large 30-ft. surface, made to scale to duplicate a 
gull's wing. It is Captain Trentice's theory that 
a surface after this pattern will prove much more 
efficient than the usual type of plane, and will 
enable fiiglit at si)eeds down to 1(1. miles an hour, 
lie has had exceptional opportunity for studying 
the.se birds, and he has observed them in free

William Evans, 81T-A I':ast Fifteenth St., Kan-

with a four-cylinder Elbridge engine. He will 
give exhibitions with it. 



Charles K. Hamilton's new biplane, of the Cor- 
liss type, is progressing. Walter Christie has the 
N-cycle ■•\ ]()() h. p. engine well in hand. This 
IS intended to weigh less than 200 pomuls. The 
inston rods are of tulmlar steel, the wrist pins, 
connecting rods and heads being bored wherever 
possible to reduce weight. The controversv be- 
tween Hamilton and (ilenn II. Curtiss is stHl in

Lewis Strang, the famous driver of automol>iles. 
has bought the imitation Curtiss biplane built bv 
I'red Shneider for (i. E. De Long, of the Elbridg'e 
Engine ( o. This is fitted with an Elbridge 4-40-(i0 
2-cycle motor. Bosch magneto. Schebler carburetor. 



ihe public interest in aeronautics has been 
turned to good account by L. E. Dare of 216 West 
104th St., New York, who recently returned from 
a tour of the country, showing priiicipallv in large 
department stores. He gathered together' large-size 
working models of all the well-known flyers, with 
pictures, etc.. to decorate the exhibit. A lec- 
turer demonstrated the models at certain hours 
every day and explained to all inquirers the busi- 
ness of every part of the machines. The stores 
featured the exhibition, which covered about 400 
sq. ft., in their advertising, and great crowds 
were daily visitors. In some cities the public 
schools attended in classes. 

Ward and Brodie are trying out the Prof. J. J 
Montgomery monoplane in Chicago and are mak- 
ing daily flights in .lames E. Plew's Curtiss ma- 
chine. 

Comparing the Gnome and tlie Adams revolv- 
ing motors. Eric Walford gives credit for the 
early conception and practical work of the Adams- 
Farwell construction and finds them similar in 
principle. While the greater lightness belongs to 
the (inoHie. the Adams has important constructive 
advantages. The power of the engine is con- 
trolled by varying the compression. A lever per- 
mits the adjustment of the inlet cam with rela- 
tion to the revolving engine. For full power the 
cam operates as usual, but otherwise the inlet 
valve remains open during part of the compression 
stroke, so that part of the gas is blown back in 
tile inlet pipe and less is compressed. This has 
the advantage that, when the engine is throttled 
down considerably, the iiressure within the cyl- 
inders does not fall very low on the suction 
strokes, as in ordinary engines, and the lubricating 
oil will not lie liable to l)e drawn past the jiisldii 
rings into the combustion chaiiilter. By this pro- 
vision one of the great ditliculties of revolving 
motors seems to lie ol)viated in the .\dams type. 
It has no exhaust pipe or inuttler. Iiut auxiliary 
exhaust ports at the l>ottom of the stroke break 
up the exhaust into two i)orlions and reduce the 
noise. The gas is not fed into th(> crank chamber, 
as in the Gnome, but into an induction chamber, 
and thence through five radial inlet pijies to the 
tops of the cylinders, so that this I'ligine does not 
lesciiible the radial-tlow turbine as much as the 
(iiHime. in which the gas travels radially outward 
through valves in the piston head, and then ex- 
pands inward, passing outward through the cyl- 
inder heads again on the exhaust stroke. — The

Gentlemen:— I have your letter of June 1st and thank you for your complimentary 
expressions. 

The Palmer Tires, with which I equip all of my aeroplanes give the best of satis- 
faction for the purpose. The light weight does not greatly impede the lifting powerX 
of the machine and the great resiliency enables me to land without shock on the 
hardest groundt and to pick up speed quickly in starting'^'. I am glad to credit a part 
of the success of my aeroplane to the Palmer tire. 

Yours very truly, (Signed) G. H. Curtiss. 



* "Curtiss-jerked a lever. The machine ghded 
along the ground for perhaps fifty yards, and 
then rose steadily, gracefully in the air. "'—The 
Outlook, June 25. 



I "Calm and cool, as unruffled as if stepping 
out of a street car. Curtiss, as he landed, called 
out, 'where's that oil and gasoline?' " — The Out-

AEROPLANES AND BALLOONS IN MEXICO 

By E. L, Ramsey. 



The Buen Tono Bleriot Monoplane Totally 
Wrecked. 

TirERE was nrrat enthusiasm disiiIayiHl ou the 
24th of .Inly to attoiid tlir trials of the 
Blei-iot moiioiilaiic, iiiadr hy Sr. Mamipl Le- 
bri.ia, the ^Mexican aviator, on the lands of 
the Kancho de Vallniena, and 8 a. m.. at which 
hour the trials wew scheduled to commence, the 
field was filled with an immense crowd, that 
anxiously and Impatiently awaited the promised 
tlishts. 

After several successful trials, which earned the 
daring aviator tremendous applause, and when the 
crowd had gone, (luite a serious accident occurred, 
which, had it not been for the agility of Sr. 
Lebri.ia. might have resulted fatally. 

This accident took place when the aviator was 
returning to the hangar after having made an 
excellent flight, which easily surpassed all others 
made thus far. making all the turns with ease and 
having maintained a good height from the time he 
started until the accident took place. As he was 
coming along, and on descending, ho struck a place 
where the mud was extremely soft and sticky, 
causing the niachin(> to skid along for (|uite a dis- 
tance and to turn over on its riglu side, and as 
the wheels sank into the mud and resisted the for- 
ward movement, the frame of the machine broke 
in two from the force of the impact, the i)art con- 
taining the motor and propeller sticking in the 
mud. Alinor injuries were received by the aviator. 

The Captive Balloon "Ciudad de Mexico." 

The captive balloon which has been on exhibi- 
tion in the Oit.v of Mexico closed its season the 
other day and ^^ ill certainly be missed as an at- 
traction. The ascensions were discontinued on 
account of the rainy season. 

Great crowds would throng the streets to watch 
the numerous daily ascensions, and many of the 
most prominent peojile of the meti'ooolis. including 
Vice-President Ramon Corral and (Jovernor Ouil- 
lermo de Landa y Kscandon. had the pleasure of 
making the trip and enjoving the beautiful pano- 
rama presented by the "N'alley of !Mexico when 
looked at from a gr"ai^ height. The weather was 
cenerally superli and the atmosphere so clear that 
(he innumerable villaiies which surround the capital 
and the cultivated fields and orchards which dot 
the valley looked like a gigantic checker board. 

On the last ascension the pilot. Sr. Manuel L'>- 
l)i-i.ia. who has also made several short flights in 
I lie Bleriot nionoiilane. took up a jiart.v of his 
frii'uds. on which occasion the balloon was freed. 
Tlie i)arty descended near a railway station, where 
n luncli which was carried in the basket of thc^ 
iialloon was served. 

Mexican Aviator Makes His First Flight. 

On .Tnly .s. in (iuadala i-ira. on the larue and level 
lands known as 'Las .Xjuntas." to the right of 
the iirivate road of the Ouadala.iara Automobile 
Iriub. where ])lenty of space is to be had for the. 
iiurp<ise, though a tree here and there makes it 
dangerous for the aviator and machine should the 
latter not be provided with guiding gear, the pre- 
liminary luiblic trials of the aeroplane ".Talisco.'" 
invented bv Sr. f,oi)ez Me.iia. a Mexican youth. 
were lii^ld. 

The machine was run along the course several 
tiiins at a urettv .good clip in order to test the 
ngine. which was imported from Europe. tbcTi 
I he a\-iator raised his elevating planes slightly 
• ind the machine rose about •". ft. and skimmed 
iliiiitr. Finallv. after several attempts, an eleva 
linn of about (\V^ ft. was attained, but on attempt- 
ini; to make a turn one of the main planes struck 
I tree and broke, which brought the trials to an 
11(1 until such ti '^e as repairs can be rnadi^. when 
iii.itlKM' demonstv-ifion will he given. 
'I'lie trial was a success, and sliowi'd fliat the 



machme would lly. The large crowd in attendance 
expressed its apjireciation bv heartv cheers and 
prolonged applause, and the voung inventor was 
warmly congratulated. 

New Aviator Will Fly from San Antonio to 
Mexico City. 

Henry Alfred Sclnvoli. a young l^'rench marquis 
who has come into prominence here through an 
inheritance of .f;200.uoo gold, is the late.?t aspirant 
tor aeronautical honors in Mexico. 

Mr. Schwob states that a biplane is being built 
for him at San Antonio. Tex., which wilt have 
radical features of his own design which are not 
used on any of the other aeroplanes, and will be 
equipped with a 140 h. p. motor, to allow 40 per

With his own hands in Europe and has also made 
several successful flights in France. lie was con- 
templating flying from San Antonio. Tex., here in 
his machine, but as he is afraid that there might 
be long stretches where water and gasoline could 
not be obtained, and as his machine is a light ex- 
perimental one and not e(|uiiiiie(l for carrying su])- 
plies, he has given up the idea and will have it sent 
by express. lie anticiiiates no difliculty in flying 
with his machine at this altitude. He expects to

or two. 

The Monoplane as a Freight Carrier. 

Perhaps the first practical adaptation of the 
aeroplane for freight-carrying purposes in the world 
is shortly to be made by .\. A. Williams, an aviator 
of Douglas, .\riz.. he having contracted with Dr. 
.T. .T. P. Armstrong, who owns a placer mine in 
the Chihuahua ^Mountains, in the Sierra Madre 
range, near the city of Chihuahua, Mexico, for the 
transiiortation of placer mining machinery from 
Douglas to his property, a distance of about .300 
miles. The machinery in question consists of 
pieces which can be made up info KMi-pound lots. 
The machine which Williams will use is a mono- 
plane. 

When the above notice was brought to the at- 
tention of oflicials of (lie Mexican government, 
immediate instructions were given to Sr. de la 
P>arra. Mexican ambassador at Washington, to 
hurry the signature of the treaty for aerial navi- 
gation, which is at present being considered be- 
tween the United States and ^lexico. The Mex- 
ican government, when proposing such a treat.v to 
Uncle Sam. not thinking, perhaps, that such legis- 
lation would be re(]uire(l so soon for the purpose 
of regulating aerial freight (ralHc.

FLYING OUT ON THE PACIFIC COAST 



THE WISEMAN-PETERS BIPLANE 

By Cleve T. Shaffer. 



EXCKPTINO power plant, this machiiiP would 
appoar at first s'lance to be an exact dupli- 
cate of the Farman machine in which 
Paulhan made his height record at Los 
Anjreles. but on closer inspection a number of 
modifications and some improvements may he 
observed. For instance, the diagonal cross stmt, 
or stay, on each skid. Curtiss lateral control by 
shoulder brace, and elevator and rudder control 
by wheel : skids on ends of plane ; skids on rear 
cell, which on striking the ground allow the rear 
edge of the lower plane to swing up and thus 
avoid injury in landing. One noticeable defect, 
to the writer's mind, is the flatness of the planes, 
the camber being only 1 in .^^6. which, no doubt, 
accounts for the large horse power and high inci- 
dent angle. It is claimed that this machine has 
flown with a r,0-.S5 horse power motor, but evi- 
dently results were not satisfactory as a 60 
horse power is now installed. 

The machine is of very neat construction and 
workmanship. thoTigh the sockets aupear cumber- 
some and have altogether too much head resist- 
ance. Except on rudder, elevator and aileron 
controls, where Roebling "aviator cord" is used, 
oil-tempered steel wire is used throughout. No. 
12 guying the planes. No. attached to skids 
and No. 6 between skids. Ferrules are used in 
fastening. Eflicient turnbuckles of their own 
design are used, a small one testing 1,14!) pounds, 
a medium and a larsre testing (stated^ 4 tons. 
They consist of a Mc.\damite body of suitable 
shape into which screws the eyes liy right and 
left-hand threads, a lock nut' on one " of the 
eyebolts is screwed against casting or body end 
and locks. 

The skids extend out in front finite a bit fur- 
ther than in the Farman. ferruled end being 
guycMl to frame in usual manner. 

Spread is 32 ft., length 42 ft., surface 372 ft. 
wei'flit S.")0 pounds without operator. 

I'liincs. — 32 X 6. lower cut out to beam for 
propeller, are double covered, ribs and beams 
enclosed with Naiad No. G ; beams are laminated 
front 1% X 21/2. rear 1 1/2 x 21/4: ribs are built 
up. nailed and glued to beams, camber 2 in.. 30 
in. liack from front edge: struts, oval, li/^ x 1 
in. center cross section : Vi x %-in. ends. Inci- 
dent angle very hich for biplane nractice. though 
measured, is not to be made pulilic as vet. 

riidsfils. — Regular Farman type — Two skids and 
four wheels, with the addition of a diagonal cross 
strut from underside of lower rear beam to skids 
in front of wheels. Chassis stmts are IVo x 2V4, 
in., cross section oval. McAdamite sockets of 
suitable angle. Holes drilled into casting are used 
for guy-wire fastening: this is not verv good 
practice unless some sort of a bushing is used. 
as the vibration of the wires wears the motal ap- 
nreciably. Am indebted to Mr. Peters for t'Ms 
information, which I believe is not generailv 
known. Skids are of hickorv 'iVz in. wide. 2^^ 
high. Wheels are 2S in. with a 2% -in. tire, 
steel rims, narrow hubs and babbitt friction bear- 
ings, are 33 in. apart on a 2 14 in. axle, held in 
place on inside by stay collar and outside by a 
cotter pin. An eyebolt set in the skid takes 
the ends of the two %-m. I.S-gauge stavs. other 
ends fastening to collars on axle. The method of 
hanging skid is ingenious: the skid passes through 
two rectangular links of '4 -in. iron, which (>ngage 
grooves on bottom of skid, lleavv leather straps, 
adiustable by a buckle, fasten the links to two 
other links of 1^4 -in. scjuia re-moulded rubbm- : 
these latter pass over axle and are held in place 
by wooden shoulders Iiolted to axle. Liyht skids 
are i)ivoted from rear lienni at each end: wires 
with a rubber elastic luedlum. to take up shock, 
run from middle of skid to front beam. 

Coiifrnls. — The elexator axis is at a jioint 12 
ft. f)iit in front, a JMc.XdaniKc- casting connecting 
(he two spars and serving as a bearing for the 
shaft. This is placed a little forward of center 
of the double-covered plane, which is flat on the 
bottom, size 3 x ,8 ft., and works in conjunction 



with a flap hinged on th(> upper rear surface. 
Three posts are placed on the front and two on 
rear. Tail jjlanes are 8 x 6 x (^) ft. apart, su])- 
ported by two skids (see general description). 
The front edge is 14 ft. 3 in. from roar edg« 
of main planes. Outrigger spars are two-ply 
laminated. 1 1/10 in. square section, struts same 
size as in main planes, 48 in. apart. 

The rudder is 4 x 6 ft., placed between planes 
on front middle strut. A cord prevents more than 
18-in. movement to each side. 

Ailerons. 1% x 6 ft., hinged to rear beam by 
thre(> hinges. 

Ste(n'ing wheel, automobile, spider bored out 
to lighten, post pivoted at center (see photo 1 
between seat and engine base frame, to which 
are mortised and bolted the Vs which hold the 
stationary foot rests. Aluminum treads are 
placed on these, giving the machine a finished 
appearance. 

The shoulder brace is laminated and the seat 
of wickerwork. 

Power 'plant. — .\ 60' horse power Hall-Scott 
8-cylinder engine drives direct a 7 ft. 8 in. Ilall- 
Scott propeller of about 4% -ft. pitch — not uni- 
form: blade 12% in. wide with %-in. camber at 
this width. Thrust at 1.400i r. p. m. (stated). 
280 pounds. Shaft ai)proxiraately horizontal in 
flight. Motor is equipped with a Bosch magneto. 
Gear water and oil pumps. Oil tank fixed to 
base of motor. Ttadiator placed over and in 
back of operator. Gasoline tank, three-gallon, sup- 
ported by wires. Engine and seat base clamped to 
beams by %-in. TT bolts. 

On .July 24 three flights of about a mile each 
were made without accident, including turns. The 
machine handled excellently with J. W. Peters pilot. 

.VERONAt'TH's is greatly indebted to the courtesy 
of the owners for allowing its representative to 
go over the machine so thoroughly and secure the 
above valual)le data for pul)licati()n. Mr. Don C. 
Prentiss and Mr. .T. W. Peters were especially 
kind. 

O'Brien Flies Farman Type. 

Clifton OT.rien. of the Pacific Aero Club, has 
a Farman-type machine. He reports having made 
several flights, longest being about a quarter 
mile. In his Last flight he rose from the ground 
in a run of 7.". ft. and while flying along at a 
height of 20 ft. was caught in a downward eddy 
that swirled around the grandstand and tipped 
him over to the left at an angle of nearly 45 
deg., desiiite his manipulation of the ailerons. 
He finally recoveri'd his lateral control, but in 
the meantime lost in the fore and aft direction 
and the machine, which was probably too lightly 
built, struck the ground violently and was 
wrecked. Mr. O'Brien escaped injury. 

The machine is 31 ft. spread by " 42 ft. fore 
and aft. Planes 31 I)y ft., curvature 1 in 32. 
Weight of frame without power plant, 376 pounds. 
Weight complete. 820 pounds. 

The power plant consists of a llall-Scott 8 
cylinder 60 horse power engine, driving direct a 
ITall-Scott 7 ft. 6 in. by 4-ft. pitch propeller. 
The thrust claimed is 28.'i pounds. A "Sunset" 
radiator of but 1 •"> nounds weight does the cooling. 

The biplane is almost a duplicate of the Wise- 
man-Peters completely described in this issue, hav- 
ing the same sockets, ribs, stmts, control and 
general dimensions and power plant. As pointed 
out by the writer in the descriiition of the latter 
machine, the small camber of the surface nec(>ssi- 
tates a greater angle of incidence and a c(irr(>- 
spondingly greater horse power. 

Leyland P.r;, ant and Louis Foi'lney. of S.ii) 
Francisco, who recently completed a large .\\v 
loini'fte l\pe muiiiinlane. wrecked the machine on 
each of ils two trials and are now at work (lis 
semblini;- the remains, having given up active 
particii>ation in the conquest of the air. Tliev 
will sell the 60 horse power auto engine with 
which the machine was eciuipjied.

THE STEVENS MONOPLANE 



By Chas. E. Schmerber. 



THE Stevens monoplane, built by Wm. Stevens, 
of Los Angeles, Cal., wbicli lacks but tlie 
motor to go on its trials, embodies some 
new ideas in monoplane construction. 

Frames. The framework consists entirely of 
steel tubing, except the ribs and lateral beams of 
wings. These are hollow wood, wrapped with 
muslin tape and glue, then wound diagonally with 
piano wire. All joints are brazed. The body is 
of hexagonal design properly braced by steel wires 
equipped with turn buckles. 

Planes. The width of the main planes is 32 
ft. over all with a depth of 10 ft. tapering to 
3 ft. at the tips. Width of rear plane is y ft. 
e in., and depth 10 ft. The total length of the 
machine is 24 ft. 

liunning gear consists of three caster wheels 
26 X 2%, spread of the front pair being 7 ft. 
6 in., all wheels being pivoted with spring suspen- 
sion. 

Propulsion. The diameter of the propeller is 8 
ft. with 10 degrees pitch. The motor has been built 
by Buel H. Green, of Los Angeles. The engine is 
an eight-cylinder set at 90 degrees, "V" type, 50 
h. p. ; the bore is lOOm/m, the stroke is loOm/m. 
The cylinders are made of high carbon steel, turned 
from the solid billet, the pistons are low carbon 
steel with cast-iron rings ; the cylinder jackets are 
of spun copper, and the cylinder heads are water 
jacketed oast iron; the valves are placed at an 
angle in the cylinder head, and are operated by a 
cross beam from the cam-shaft, which lias four 
double throw cams, each cam operates the valves 
for two cylinders. Connecting rod's and crank 
shafts are made of Vanadium steel, the crank 
case is aluminum, carrying at each end large 



annular ball-bearings which support the crank- 
shaft, P. & S. ball-bearings also are used to carry 
the cam-sh'aft as well as for rollers in the valve 
plungers. Mr. Stevens is also using a special turn- 
buckle which Green is making for the aeronautic 
trade. 

Both inlet and exhaust valves are of generous 
proportions, being 50m/m diameter, so as to 
offer as little resistance to the passage of the 
gases as possible. 

Control. The control of this monoplane em- 
bodies some new ideas, the lateral stability being 
maintained by the main supporting planes in this 
way : The planes are pivoted in their center of 
pressure and independently of each other, and 
can therefore be offset, viz. : one plane can be 
given a greater angle than the other. The scope 
of angles is from 3 degrees negative to 18 d'egrees. 
Both the elevating and offsetting of these planes 
is ingeniously effected by the movement of one 
handlebar in front of the aviator in such manner 
that swinging this handlebar upwards in a verti- 
cal plane gives a larger angle to the plane on that 
side, thereby righting the machine. By pulling 
the handlebar on the left towards you, gives the 
planes an angle of 3 degrees negative and the 
opposite movement gives 18 degrees positive. As 
can be seen by the photograph, the aviator sits 
over the rear plane, back of the rear wheel and 
just in front of the direction rudder. 

The weight of the machine when fully equipped 
and including aviator will be l.OOO' pounds. 

The double surface direction rudder is operated 
by the feet on a cross lever connected up by wires 
through pulleys.

AT THE LOS ANGELES AERODROME 

By Prof. H. LaV. Twining. 



Three machines now at the Los Angeles Vero- 
drome are endeavoring to fly. J. J. Slavin, with 
his biplane, has made a flight of 50 ft. The 
aerodrome is one mile in circumference, thus mak- 
ing It 1,700 ft. in diameter. Tart of this distance 
is taken up by the motordrome track and the 
inner fleld fence. This leaves but 1,000 ft. clear 
space m length. This is too restricted a space 
for amateurs, as it takes a large part of the dis- 
tance to clear the ground, and one must alight 
within a small distance to avoid running into 
the fence. 

A ti-ack outside of the enclosure has just been 
completed. This track is over a mile in length. 



T p to th,. prcsc-nt time a thrust of l.S(» potuids has 
been obtained at 1.400 revolutions. 

(xeorge i)eu.ssler has built a machine of the 
l^arman type, equipped with a Mitchell automo- 
bile engine of 30O pounds weight and :i(i h p 
lie has been off the ground with this machine 
and in a try out on .July 31 the front control 
broke. I he wind blew it back into his face 
and cut the bridge of his nose. He escaped other- 
wise unhurt. 

The Greer-Robbins machine is a monoplane of 
peculiar construction. This machine is equipped 
with an "N" model Ford automobile engine If 
liMs ninde a flight of some 9.3 ft. This machine 




The Aero Club of California's Aerodome 

:iiiU Mr. Slavin intends to try out his machine on 
this track on Aug. 5. Slavin's biplane differs from 
others in the arrangement of the main planes, in 
order to secure automatic lateral stability. The 
resistance under one plane causes that plane to 
shift the opposite plane automatically. The same 
is true of the fore and aft stability. 

The Eaton-Twining machine has been running 
around on the ground endeavoring to fly. This 
machine is a monoplane of the Bleriot type. It 
differs from that machine in having sliding ])lanes 
for securing lateral stability, inst(>ad of ailerons 
or warping. The machine is making daily jumps 
of 10 to 5(^ ft. On one occasion it rolled over on 
its back. Warren S. Katon was driving the 
machine. The main planes had not yet been put 
on. In making a turn the macliini> skidded and 
turned over sideways, landing on its back. Warren 
escaped unhurt. 

On another occasion the axle broke, and as the 
iiiachine was traveling some 25 miles an hour, it 
pitched over on its nose. Warren Eaton was the 
ilihcr and he again escaped unhurt. 

Mr. Slavin's machine is equipi)ed with a Werner 
inotcir, made in T os .\ngeles. It is a .'10 h. p. 
t cylinder water-cooled motor. The Eaton-Twining 
mnihine is equipped with a Ford automobile en- 
yiiic, "T" model. 4-cylinder water cooled. '22Vz 
h. ]i. Total weight of power plant is 200 pounds. 
Weight of machine with aviator is 700 pounds. 



The Eaton-Twining Machine 

is in-obably the second machine belonging to a 
member of the Aero Club of California to leave 
the ground, the Gill bipUine being the first. The Gill 
machine is a Farnian type so that the Greer-Robbin.s is the 
first monoplane invented tty a inenil)er of the Aero Club 
of California to clear the ground. There are some 
ten other machines at the "aerage" in various 
stages of construction.

I have reail your editorial note for .July with 
admiration and enthusiasm, and note your" .splen- 
did advertising ])atronage, and its logical nature, 
with real aslonishnK^il. Your periodical has been 
as complete, world-wide and nearly as wonderful 
as the triumph of Wilbur and Orville Wright. 

1 am only a literary man of (iO ; I have stuck 
to my trade and have beheld the death of nearly 
all illusions. Yet the scientific progress since 
1S7<!. the phonograph, telephone, the dynamo, spec- 
troscope, turbine. X-ray and radio-activity, and 
finally the Wrights, have kei)t me alive to the In- 
teresting character of this otherwise unpleasant 
world. Wonderful ! Wonderful ! One may be an 
incpiiring little child at 60!

Aug. 15. — The success of the Wright Meet 
which opened at Asbury Park, August 10', un- 
der the auspices of the New Jersey Aero anrt 
Motor Club, was marred on the very first day by 
the injuring of several spectators when Walter 
Brookins smashed his machine at one end of the 
grand stand. The machine used was the first 
Wright macliino to bo seen in public with wheels 
and ihe fliglit was the very first one that had been 
made. The wind at the grounds was very strong and 
at times the aeroplane almost stood still. Gliding 
down from a height with the engine shut off. Brook- 
ins was just about to touch the ground, so eye 
witnesses state, but right in front of him were 
newspaper men and photographers. To avoid 
these, Brookins. with the little headway he had, 
turned up again to clear them but he did not 
have speed enough. Turning the machine quickly 
toward tlie most available spot, it landed on its 
nose :and was smashed, and Brookins somewhat 
hurt. 'IMie spectators who were injured, and sev- 
eral quite seriously, were struck by the machine 
in making its landing. The highest wind velocity 
between 1 :00i P. M. and (> tOn P. M. that day. ac- 
cording to the nearest weather bureau station, at 
Long Branch, was 24 miles an hour. Hoxsey, im- 
nuediately after the accident, went up for five 
minutes, and one of the hot air balloons was sent 
up. 

The Wright aviators at the Meet are: Walter 
Brookins, Prank Coffvn, Duval La Chapelle, Arch 
Iloxsey and Ralph .Tohnstone. 

Up to 3 '.OO' P. M. every day there is an exhibi- 
tion of kite flying given by A. E. Wells with his 
outfit of all kinds of kites, and by the Signal 
Corps of the New .Jersey National Guard using 



Eddy kites. Every day that the weather permitted 
Fred L. Owens has been going up in his dirigible. 
.Johnny Mack gives each day an exhibition of single 
and double hot air balloon ascents with para- 
chute drops. The field is one of four acres enclosed 
by a 15-ft. canvas fence. 

The accident seemed to double the sale of seats 
the next day when 10,000 persons were present. 
Wilbur Wright came on from Dayton to visit 
Brookins and saw Johnstone and Iloxsey fly, and 
in a contest, alight in a pre-arranged space. 

PARACHUTE JUMPER KILLED 

The third day saw the death of Benny Prinz 
who was killed in making a double parachute 
drop, the second parachute failing to work. He 
must have fallen from a height of about l.OOOi ft. 
Two men were in the balloon, Samuel Ilartlaud, 
and Pi'inz. Harlland had already cut loose from 
the lialloon and reached the ground safely in the 
single drop. Governor Fort was present and saw 
the flights, leaving just before the fatal accident. 

On this same day Hoxsey and Johnstone were 
both in the air at the same time making short 
turns and dips, and cutting fancy figures. Hox- 
sey went up to 1,800 feet, the highest that he has 
yet been. 

Johnstone made his longest flight Saturday, re- 
maining up ?>5 minutes and attaining an altitude 
of .".OOO ft., the end of his descent Iteiug at a 
sharp angle with the engine cut off. I>uriim- tbi- 
flight the dirigil>le was sailing around and IIoxm) 
did "stunts" many hundred feet below Jolinstmu 
Coffyn also flew. 

Sunday there was no flying and' to-day m r:iin 
st(irm prevented. The meet has six more days to 
r\ni.

H. P. BY REACTION TEST 

(Concluded from page 7s) 

liot. sultr.v atmospjiere to dry, wet or cold, or 
till' pifect of rarified atmosphere at high altitudes; 
in fact, the c'ombinations of tests which may be 
made are numerou.s. 

Your author has not had the time or means 
to prove out his theories in actual practice, Ijut 
cheerfull.v makes these suggestions of the pos- 
siliilities with the simijle little devices previously 
mentioned. Your author also contends that the 
horse power of a large majority of the present 
aeronautical engines rarely comes up to the rating 
((noted by the builders, and, still worse, cannot 
as a rule continue to run for an extended period 
of time. lla\ing no convenient means at hand 
to test his motor, the purchaser often does not 
know the power his motor actually develops, 
nlthongb the fault may not always lie in the 
nioicr. but ])ossibly du(> to numerous conditions 
and causes hard for the layman to locate. 

Yoxn- author further contends that the present 
i.vije of th(> four-cycle engine is not ideal for 
aeronautics and hopes at a later date to demon- 
strate this theory by practice. The extreme light 
weight is not so essential as the propeller pull 
per horse power, as upon this feature in a large 
measure depends the ability to fly with the pres- 
ent type of plane, but do we get the pull on pro- 
peller desired at normal speed of engine? 1 
think not.

Omaha, July 23-27, 
By T. T. Tuttle. 

The Omaha (Neb.) meeting, on July 23 to 27, 
was held under the auspices of the Aero Club 
of Nebraska, and was particularly interesting ow- 
ing to the fact that every type of craft that 
navigates or sails the air participated. There were 
two hot-air balloons, a captive, a free balloon, 
a dirigible balloon and three Curtiss aeroplanes 
in the air each day. 

The chief attractions, however, were aviators 
rjlenn H. Curtiss, .T. C. Mars. .1. A. D. McCurdy 
ind Eugene B. Ely. 

The weather made it a difficult task for the 
iviators to open the first day with their best 
vork. 

Weather conditions on the second dav were 
ibout the same as the day before, but in spite 
)f this handicap all aviators made flights. The 
)rognim closing with a spectacular race be- 
ween Curtiss and .Mars. In the evening the 
J. S. Dirigible No. 1 left Eort Omaha with Lieut, 
laskell in charge and ((uild l)c plainlv seen 
rom the aviation field. 

U. S. DlRICJIBr.E BRKAKS CR.\NKSH.\FT. 

About 0:30 P. M.. .July 24, Dirigible No. 1, 
I'ith Lieutenant W. X. Haskell, Signal Corps, as 
'Hot, and Sergeant Ward as engineer, started from 
'"ort Omaha, Neb., for the Aviation Field. A good 
tart was made and the lialloon rose about 200 ft. 
Q the air — evei-ything apparently working in 
rst-cla.ss condition. .V. couple of circles over the 
'ort were made and then the balloon was headed 
n- the Aviation Field about four miles away. The 
onditions were very good with onlv a slight wind 
ehind the balloon. Shortly after starting and 
till while over the reservation, the engine stopped 
w to a j)reak of thi' crank-shaft. This precluded 
ny further attempt with the dirigible until re- 
airs could be made. 

On .July 20, captive l)aIloon, No. 9. was inflated 
1 the balloon house at Fort Omaha and towed 
ivout 2% miles across country to the Aviation 
ield. This was accomplishe<l in 1 hour and 50 

inutes. Fpon arrival at the Aviation Field the 
Uloon was put in operation and several ascents 
adi' l)etween fi and 7 :30 P. M. Mr. Glenn Cur- 
ss made s(>veral flights in his aeroplane around 
le lialloon while It was in the aii-. 

On Monday the wind increased in velocity and 

was impossible for the aviators to make" any- 
ling more than short straightaway flights. 

XEW SHORT .ST.\UT RECORD. 

The government cajitive balloon was blown 
ose from its moorings late in the afternoon 
id landed a mile from the grounds after the 
p cord had been pulled automatically when it 
rked loose from the winch wagon on the 
•ounds. Many thousands of .spectators stuck 
Uil the last announcement was made that "wind 
lecks" would be honored the following day at 
e gate. It %vas in the face of this wind "that 
ars rose into the air in his four-cylinder Curtiss 
'-30 horse power machine after a run of 53 ft, 

in., establishing a new U. S. record for short 
art and earning thereby a silver trophv offered 

a local paper. 

Tuesday and Wednesday, the fourth and fifth 
ys, the weather conditions were more suitable 
r good flying, the wind velocity having dropped 
wn in the late afternoon on each of these days, 
irtiss. Mars and Ely drove their machines "at 
and each day Curtiss and Mars raced around 
e field at a height varying from 100 to 300 ft. 
le attendance on each of the last two days 
is more than 10.000. On Tuesdav evening 
e captive balloon was refilled and made" an ascent 
th Mrs. Mars, wife of the aviator, and W. H. 
tton, of the Curtiss company, as passengers. 
.Vt the close of the meet Curtiss was awarded 
one of the local jiapers a heavy silver water 
I pitcher for making the mos"t daring and 
'Ctacular flight during the meet. This flight 
s made on the first day of the meet when 
rtiss flew out of the grounds and out over the 
uitry, which was covered with fences, gulleys 
■il trees, in the teeth of almost a gale. 



Pittsburg (Pa.), Aug. 4-6. 
By Earl O. Guntheb. 

The Pittsburg Aero Club held its first meeting 
Aug. 4 to 6 at Brunot Island race track. There 
were four biplanes present, three Curtiss and the 
Baldwin. The aviators were Curtiss, Mars and 
Capt. Thos. Baldwin. The official timer and re- 
corder was Augustus Post. 

The first day of the meet there was only one 
straightaway flight made, by Mars in a gusty 
wind of 35 miles an hour. 

The second day all three aviators made flights 
Mr. Curtiss making the first and most spectacular! 
His first flight, in a wind of 25 miles an hour 
circled the mile track twice, with remarkable 
skill at balancing in a gusty wind. His longest 
flight for this day was about six miles. He akso 
made trial for short starting, arising in 81 ft "* 
in., officially measured. The wind was very 
gusty not allowing very much flying this day. ' 

.\.\OTHER NEW .SHORT ST.VRT RECORD FOR D. S. 

Mars was able to get ofl: the ground in 3.". ft 
making another new short start record 

The third day of the meet was windy and 
the aviators were hampereo very much "by it 
Curtiss again made the most spectacular flights 
Dying out over the river. Mars made a series of 
short circular flights around the mile track. Capt 
Baldwin made only straightaway flights. Great 
enthusiasm was created bv the flights of Curtiss 
and Mars, Curtiss flying above Mars and in the 
same direction and at the same time. 

The last day of the meet broke all records for 
crowds at the track and thousands of people were 
on the surrounding hills watching the flights. 

Decatur (Ills.), July 16-17. 

Charles F. Willard (Curtissj flew before good 
crowds m Decatur, Ills., July 10-17. On the flrst 
day he made a cross-country out of the field and 
back, estimated by local experts as 30 miles, in a 
flight lasting 40 minutes. 

St. Louis Show Date Changed. 

The date of the aero show at St. Louis has 
been changed from Octol)er to November 17-24 to 
avoid conflict with outdoor events on Hempstead 
Plains. 

Toronto, Canada. 

There were nine days of flying, participated in 
by Kalph Johnstone (Wright), Count Jacques De 
Lesseps (Bleriot), Duval La Chapelle (Wright), 
\Valter Brookins (Wright) and Frank T. Coffyn 
(Wright), July S-16, except Sunday. Count De 
Lesseps flew from the grounds, which were lo- 
cated on the Trethewey Model Farm, about eight 
miles from the center of Toronto, over the heart 
of Toronto and back, duplicating his Montreal 
feat, and once flew to a height of 2,700 ft. Ralph 
Johnstone made two remarkable flights and seven 
in all, once battling an extremelv high wind 
at an altitude of 3,400 ft., and on another flight 
executing all sorts of maneuvers of which the 
Wright aeroplane is capable, aerial "roller coast- 
ing," sharp circles and spirals, skimming the 
ground, etc. The newspapers divided the honors 
between Johnstone and Count de Lesseps. Five 
thousand to flfteen thousand daily was the at- 
tendance. 

BI.ERIOT LANDS IN TREE. 

The Carruthers "Bleriot," flown by Sti-atton, 
ran into a tree. He lost consciousness during his 
jump and when he came to his senses he found 
himself in the top of a pine tree 30 ft. from the 
ground. He said he did not know how he got 
there, tit was funny." 

Samuel F. Perkins, whose specialty is kite and 
banner flying, filled in all gaps in the program. 
The banners could be seen from incoming trains 
and indicated the location of the grounds. Be- 
fore and during the flight the kites could be 
seen high in the air. These now are one of the 
necessities of aviation meetings. Harvard is the 
next on the list for the kite exhibition. Here he 
will attempt to lift a man up by kites. It is esti- 
mated the pull will be about l,500i pounds, taking 
10 or more 15-ft. kites.

St. Louis National Novice Meet. 

BY K. PERCY NOEL. 

Although eight machines were on tlic field the 
opening day of "First National Aviation Meeting 
for Novices," July 11, only two got off the groimd 
during the week and the prizes were all won by 
one man on account of an accident to Howard W. 
Gill, while practicing on July 12. J. W. Curzon 
(Farman) won $800 in three prizes by flights 
made July 14 and l.). There was no competition 
on July 12, 13 and 15. On July 11 Gill flew 
25 yards and landed in a ditch disabling his 
n:achine for the day. On July 12 while practicing 
in the evening, Gill flew half a mile outside the 
held. Something went wrong with his elevating 
control and in his inexperience he dropped from 
40 ft., smashing half of the machine. He piclvcd 
himself up but was confined to the hospital for 
three days. 

July 14 was a good day for Curzon, flying 
92 yards on his first trial and 113 on his second, 
winning his debut prize of $100. Later he won 
the $100 daily prize for the first flight of 200 
yaixls, traveling ."{22 yards straightway after 113 
yards and then touching. Rain interfered on 
July 15. 

On July 16 Curzon made a flight of about 500 
yards, winning the $100 daily prize. The meet 
was continued July 17. but wiud prevented flying 
until after official timing closed, then Curzon flew 
186 yards. Curzon and Gill have both made per- 
manent headquarters on the Washington Park 
aviation field of the Aero Club of St. Louis. 

On August 13. Ilillery Beachey, flying one of 
Gills' biplanes without front elevator, made two 
circuits of the course without stopping, about 
1 % miles. 

Dr. J. J. De Praslin, of Nicaragua, has ordered 
material from the Aeronautic Supply Co. for the 
construction of an aeroplane here. 

Chas. Kulmo had a monoplane that was equipped 
with a Curtiss 8-cylinder 40 h. p. engine that 
looked very promising, construction and designing 
above the ordinary. 

Robinson's monoplane of the Bleriot type, 
equipped with a 3-cylinder Elliridge motor, did not 
get up enough speed to make a getaway from 
terra flrma, although the construction was very 
good. 

Zehler's monoplane was a machine that differs 
from the general run of flyers, and if you are 
able to get a photo of it,' you could probably under- 
stand same l>etter than the maker. Equipped with 
a 4-cylind(>r 4-cycle marine engine, it was unable 
to make a speed of more than five miles per 
hour. 

Suarlinii's Curtiss type biplane, equipped with 
a 4-cycle i:iliriilge was very neatly made and 
looked urcimislng. It was mounted on Farman 
. type running gear. 

Curzon's "Farman" biplane seemed as though it 
had seen better days, although of the standard 
type of a past season was still in the ring. The 
big Vivinus motor does not give power enough to 
enable the machine to make extend'Cd flights. 
Those made have been but short ones. 

SEVEN AEROPLANES SMASHED BY..WIND. 

A few days' after the Novice Meet ^ St. Louis, 
a terrific storm blew down the tent Which housed 
the aeroplanes, demolishing 7 machines. Nothing 
was saved of Curzon's Farman but the engine and 
propeller. Ploward W. Gill's machine was un- 
harmed as it was housed in a wooden shed. 

Detroit. 

At Detroit. La Chapelle, Hoxsey and Brookins 
made sensational flights and delight(>d the manage- 
ment and large crowds. The Wright machines 
will return to Detroit in September. 

Lexington, Ky. 

J. A. D. McCurdy filled the Curtiss date at the 
Lexington, Ky., State Fair, Aug. 7-13, making 
several flights each day of the exhibition. 

Grand Rapids. 

Mars ^Curtiss) was to have flown here July 
16-17, but the high wind prevented flights both 
days. 



Ne'w York, Aug. 19-21. 

Glenn H. Curtiss, J. C. Mars, J. A. D. Mc- 
Curdy, C. F. Willard and Eugene Ely are sched- 
uled to give a 3-day exhibition at the Sheepshead 
Bay racetrack, New York. Aug. 19-21. 

Eugene B. E:iy, a Curtiss aviator, began prac- 
ticing at Sheepshead Bay racetrack in preparation 
for the exhibition on the 10th, using for the flrst 
time the 8 cylinder Curtiss engine which is slowly 
being installed in all the exhibition machines. 

.T. A. Douglas McCurdy, former member of the 
Aerial Experiment Association, who with P. W. 
Baldwin, another member, formed the Canadian 
Aerodrome Co. at Baddeck, Nova Scotia, has signed 
a contract with Glenn Curtiss to fly a Curtiss 
machine. His flrst appearance was at Omaha, 
July 23-28. From there he went to Lexington, 
Ky., Aug. 7-13. Eugene Ely of Portland, Ore., 
who has been flying a Curtiss machine for E. 
Henry Wemme, Curtiss agent of that city, is an- 
other addition to the Curtiss troupe of aviators. 

Augustus Post, former secretary of the Aero 
Club of America, has bought a Curtiss machine 
under a special arrangement, and will fill exhibi- 
tion contracts wherever they do not conflict with 
Curtiss' interests, or will fill engagements obtained 
l)y Curtiss. He will begin pi-acticing under the 
al)le tutorship of Charles V. Willard, using a 
machine which Willard has been putting in shape 
in the Aeronautical Society's shed at Mineola. 

Clifford B. Harmon has ordered a fast machine 
from Glenn Curtiss, in which it is expected he will 
install his Gnome engine for trial.

promised to be held in addition during tlie week, 
liave apparently not developed very far as yet. 
Not a single announcement of prizes has been 
made, and it is now very late for foreigners to 
figure ahead. Unless announcement is made very 
shortly, aviators of other countries will have made 
their arrangements for that period at various Eu- 
ropean meets. 

Following on the heels of a disagreement with 
(Jage E. Tarbell, who was the Aero Club's general 
manager for the meet, Belmont racetrack was 
made the place for the Gordon Bennett aviation 
race and other events, instead of Hempstead Plains 
as at first planned. L. L. Gillespie stated to-day, 
Atig. 15, that the amount figured to be necessary. 
$110,000, had all been raised. "This will be the 
biggest meet of the year," Gillespie said, ".'fSO.OOO 
being offered by the committee in prizes" ; and 
that the magnitude of the affair will be such that 
no aviator, American or foreign, whether for finan- 
cial reasons or for the sake of glory, can afford 
not to take part. Referring to the rumors that 
Curtiss might not be on hand to defend the cup 
by reason of the fact that arrangements are al- 
leged to have been made that the Wright company 
shares in the gate receipts, Mr. Gillespie said that 
Curtiss would, of course, be asked to take part, 
but that the acceptance of the invitation was up 
to Curtiss and he could do as he liked. 

The meet will be financed by the Aevo Corpora- 
tion, Limited. August Belmont has been chosen 
president of the meet. The executive committee 
is composed of the chairmen of the various com- 
mittees, as follows: L. I>. Gillespie (Finance 
Committee), Allan A. Ryan (Arrangements Com- 
mittee), J. C. McCoy (Aviation Committee!, and 
.Vndrew Freedman, chairman. 

Five Wright aviators will fly. and it is e.xpected 
eight or ten foreigners will appear. 

At the Aero Club of America no information 
could be had as to the foreign contestants. 

F.\.ST WRIGHT MACHI.NE. 

The Wright company is building a special racing 
machine which may be entered to defend the cup. 
At the same time. Curtiss is also working on a 
machine designed to be capable of beating the 
speed expected to be made by others in the Gordon 
Bennett. It is very likely that to defend the cup 
successfully a machine will have to go 70 miles 
an hour. The lOO h. p. Bleriot made GG m. p. h. 
at Rheims in July. Clifford B. Harmon has or- 
dered a Bleriot, in addition to his Curtiss. 

Clifford B. Harmon Adds $i,ooo to Times 

Race. 

Clirtord R. Harmon, chairman of the national 
council of the .Vero Club of America, has offered 
•$1,000 in cash or plate to the contestant in the 
Chicago-New York race who first covers 500' miles 
in the first 50 consecutive hours. 

Gordon Bennett Balloon Race. 

Six countries hav<' ciitcrod 14 balloons in the 
Gordon Bennett race on October 17. as follows: 
France '■',. Germany o. Italy "J, Switzerland '2. I>eu- 
mark 1 and U. S. 3. Only the German entrants 
have been named to date. They are : Ilauptmann 
Von Abereron, who was in the 1907 Gordon Ben- 
nett at St. Louis, Lieut. Vogt, Ing. Hans Gericke. 

In the elimination race to pick the .\merican 
team, Sept. 17, .Man R. llavvley and I'ost will have 
one balloon, (". B. Ilarmim and ("apt. Baldwin a 
second and possibly A. II. Forbes will be sulticient- 
ly improved in health to take part. A. T. .Vther- 
holt from Philadelphia will be another. St. Louis 
is likely to have more than half a dozen en- 
ti'ants. .V. B. Lambert is sure to go in, G. I.. Bum- 
baugh, St. L. Von Phul, H. E. Honeywell and W. 
F. .Assman are strong probabilities.

NEW^ CURTISS AEROPLANE

THE NEW BALDWIN 



Walden Accident 



THE new Curtiss biplane, built especially to 
specifications of Charles F. Willard, tbo 
assomblin-j; of which was completed at the 
Aeronaut ical Society's shed at Mineola. L. 
I., the nth of Auijiist. differs from the standard 
Curtiss niachin'' only in size and minor details of 
construction. 1'he accompanying drawing gives 
complete meas\ireinents : 

Main Plaiirs. — These are 32 ft. spread by .5 ft. 
fore and aft. spaced 5 ft. apart. The other Cur- 
ti.ss machines .spread 26 ft. 3 in. by 4i^ ft. the 
other way. The main cell is divided into five sec- 
tions for sbjijping purposes. These sections of 
the lateral beams join as shown in the following 
sketch : Tlie curve of the ribs is 1 in 20, the deep- 
est point 3 in., coming 18 in. back from the front 
edge. The Baldwin rubberized linen covering, 
placed on top of the ribs, is made in panels .5 ft. by 
ft ft. (5 ft. bv S ft. In the center panel) and 
laced to the large ribs (which come at strut points) 
through holes Ihei-ein. The cloth is tacked on top 
of the intervening smaller ribs with large-headed 
brass tacks thi'ougb a strip of black tape. The 
whole main cell is stayed in the usual manno- 
with Roebling "aviator" cable. All ribs, even in 
the ailerons and rudders, are laminated ash and 
spruce. The spruce lateral beams of the main 
planes are solid. All ribs and beams of rudders 
and ailerons laminated ash and snruee. 

Rudders and Other Siirfncen. — There is the usual 
double plane hoi'izontal rudder, or "elevator," in 
front, spreading 7 ft. by 27 in. by 27 in. The 
surfaces of this are double — i. e.. the cloth Is on 
both sides of the ribs. The same is true of the 
vertical rudder in the rear, 3 ft. high by '.',() In. 
the other way : and the fixed horizontal plane in 
the rear, measuring 7 ft. by 30 in. The latter has 



a slight curve, the depth of which is % in. at a 
point one-third bade. The elevator has the same 
curve running back from the front edge, but is 
cut off at 27 in. 

Htahilitij. — This is secured by ample-sized "aile- 
rons," ]0 ft. spread by 2 ft. 9 in. length. Instead 
of having the customary two wires (L), top and 
bottom, running to one point, joining, and thence 
over the pulleys to the shoulder brace, double- 
sheave aluminum pulleys are used and both wires 
run around the sheaves and then join, giving addi- 
tional strength. 

The control cables from the ailerons run through 
pulleys on top of the lower plane and under the 
uijper plane to the hinged steel tube liack of 
shoulder brace. Leaning tp tbe high side of the

machine when it tilts pulls the aileroii on the 
low side down (and on the high side up), increas- 
ing the lift on the low and decreasing it on the 
high. 

I'^teerinfj. — Steering up or down is by the usual 
movable column ; pushing forward steers down, and 
pulling back steers up. A bamboo rod runs from 
the column to a short mast at the fi'ont edge of 
the elevator for this purpose. The vertical rudder 
control cables run over pulleys at the end of the

Willard Carries Three Passengers— United 
States Record. 
Mineola, Aug. 14. — Charles F. Willard to-day 
established an .\merican record for i)a.s.senger car- 
rying at the Mineola tield when he look up with 
him II. V. Patterson. Harry Willard and .V. Albin. 
Starting from the Aeronautical Societv's shed, he 
flew at al)out 15 ft. above the ground as far as the 
grandstand, a distance of a quarter mile. The 
machine, a Curtiss of larger size than usual (de- 
scribed in this issue), had only been assembled 
two days before aiul made its initial flights. The 
four men weighed :;T5 lbs.. th(> macliine is esti- 
mated at (•>5(i. and with the balance in gas and 
oil, made u)) about 1.2(H) lbs. total for .'520 sq. ft. 
of supporting surface. Other flights were made 
by Willard alone. The day before several flights 
were mad<', on<' of 12 miles across country, and 
he carried two passengers on one trip, .1. C' Mars 
and his brother. Harry Willard.

he broke a rear wheel. By reason of lack of space 
the description of his machine is held over for 
another month. A feature of the Frisbie machine 
is the two El Arco radiators, placed on either side 
of tlie operator. This is the first time that two 
ladiators have been used. 

Philip W. Wilcox also made his debut in his 
l''arman-tvpe biplane with a Rinek 50 h. p. engine, 
lie circled the field at a . height of 25 to 100' ft., 
and the machine appeared the most stable of any 
on the grounds. The machine was tried out twice 
before, by Lewis Strang and by Hamilton, but 
each time the running gear gave way. Full de- 
tails will appear later. G. E. De Long, treasurer 
of the Elbridge company, had a slight accident, 
breaking a wheel, in his first trials on this day. 
\V. L. Fairchild has received an Emerson engine 
and will shortly begin trials with his monoplane. 



The Capt. Baldwin Biplane. 

Captain Thomas S. Baldwin has made some chaiiges 
!n hisbipUne which he has been tiyingut Mineola forborne 
lime. TlieCurtiss 4-cyliiider engine has been replaced b> 
one of 8 cvlindeis with an A. L. A. M. rating of 5Li 
h. p., though 01 h. p. has been claimed for a 
similar engine. The Curtiss propeller has been 
replaced by a Requa-Gibson ariven direct. The 
engine, of 'course, has been placed higher up iur 
stead of being situated as formerly on the lower 
plane and driving by chain. Formerly the pro- 
peller was ahead of the main planes and the avia- 
tor sat on a level with and just bac'.; of the lower 
plane, as illustrated in the May number. The 
vertical stability surface above the upper plane 
has been left otf temporarily, Capt. Baldwin still 
believing in its possibilities. 

Though larger in spread than the planes of 
the Curtiss machines, the ribs are standard Cur- 
tiss. The surfaces are single Baldwin rubberized 
silk, laced to the main ribs, and tacked to the 
front lateral beam. A wire runs through a pocket 
in the cloth to form the rear edge. The spruce 
lateral beams are 1% by 1%, flat with half- 
round edges, which makes the cross section nearly 
elliptical. The struts are 2V4, in. by 1 in. fish- 
shaped of spruce. These narrow down to 1 in. 
round where they fit in the sockets. Koebling 
wire cable 1/lOth diam. is used to stay the main 
cell, as well the forward and rear construction. 
In place of the two rear center stru s sui 1 tubing 
is used and to these the horizontal brums forming 



the engine bed are bolted. Diagonal steel tubing 
braces are also used at this point. The two front 
center uprights are 3% in- by 1 in. 

The front horizontal rudder, single surface, with 
a curvature of 1 in. in 32, Is stayed by wire 
cable from 18-in. masts, one on each side. The 
frame of the rudder is covered both sides with 
cloth, tacked to the ribs. The ribs in the rear 
cell, or tail are covered both sides with cloth. 

The rear three feet of the tail cell is so ar- 
ranged that the angle of incidence may be changed 
by tightening one set of guy wires and loosening 
the others. This part is hinged on the front 
eighteen inches which remain stationary. The 
control of the ailerons is by a shoulder brace, and 
the rudder by turning a wheel, similar to the 
system employed by Curtiss. All wires running to 
the rudder and controls instead of passing over 
pulleys are run through copper tubes, bent to the 
required curvature, as described some time ago in 
.Vekoxautics. The weight is around »i70 lbs. 

The equipment includes Palmer tires, Bosch 
uiayneto, and El .Vrco radiator. 



Dr. H. W. Walden's Monoplane. 

l»r. II. W. Walden gave .his nicmoplaue — the 
third machine he has built — its lirst trial on 
.vug. 3-7, with disastrous results. In .iust one short 
initial try three ribs and one collar-bone were 
broken. ' \ud then, to make matters worse, a 
none-too-kind female nurse at the local hospital 
insisted on plucking from his lips with unneedful 
force, a consoling cigar which had been given him 
at his request just after the accident. Then he 
lapsed into unconsciousness, which may or may not 
have been a direct result. Then, again, it was 
found the hospital was shy of bandages, all hav- 
ing been used up on the previous aviator. 

In this first attempt the machine got oft' the 
ground all right and the new stability device 
seemed to work perfectly. The lateral beam of 
tubular steel on which rotate the two elevators 
was too weak and bent up, shooting the nose of 
the aeroplane quickly down, so that the aeroplane 
struck on its front wheel, with the tail vertically 
in the air. the front lateral beam pinning Dr. 
Walden to the ground. 

DESCRIPTION UF THE .MACHINE. 

The main supportitig plane spreads 26 ft. by 7 

ft. in depth, and contains, allowing for the portion 

cut away for the propeller, 165 sq. ft. The lateral 

beams, of spruce, are in five sections, joined

together by sleeves of steel tubes. The ribs are 
of "I" cross section, the horizontal strips % in. 
wide, the whole rib tapering front and rear from 
3 in. at greatest height. The vertical part of the 
rib is bored full of holes throughout its length. 
The strips on top and bottom' are screwed and 
glued on.. The rib.s follow a parabolic curve from 
the front beam to the rear edge. For in. for- 
ward from the front lateral beam the surface nar- 
rows to a point. The greatest depth of the curve is 
4% in. at a point one-third back from front edge. 

Tail Plane and Eleraior. — .\t the rear is a fixed 
surface of I.t sq. ft., with a movable section at 
either lateral extremity, both totaling another 15 
sq. ft. These are curved in the same ratio as the 
main plane. These latter pivot about a latei-al 
steel tube one-third back from forward edge. From 
a short mast running through each of these wires 
run along the "fuselage" and over the pulleys 
over the front wheel and fasten to the steering 
column. Pushing forward on the steering column 
steers down, and vice versa. All surfaces are 
covered both sides with Naiad linen. 

Rudder. — The vertical rudder has a surface of 
7% sq. ft., and is operated by turning the steer- 
ing wheel left or right. 

StaMlitp. — A new scheme for automatic lateral 
stability has been devised and patented. This 
consists of small planes inclined at an angle of 
about 45 degrees, placed on a rectangular frame 
on top at the extremities of the main surface. 
Bach small plane is hinged near (H) its rear and 
near the forward end is a spring (S). If the 
machine starts to slide to one side or the other, 
the increased pressure is designed to cause the 
front end of the little plane to raise up against 
the spring's pull and present a greater angle to 
the wind. The spring holds the plane normally 
egde into the wind. This is illustrated herewith. 

Poirer Plant. — .\n Anzani three-cylinder air- 
cooled motor of 25-.S0 French h. p., mounted or 
hung in a frame of tubing, placed below the rear 
lateral beam, drives direct a fi-ft. propeller. One 
of those used was a Requa-Oibson of 4-ft. pitch, 
and the other a Brauner of 4-ft. ?.-in. pitch. 
There is no throttle to regulate the G. & A. car- 
buretor, but a lever on tho engine is utilized to 
lift the valves, permitting, when occasion demands, 
the propeller to turn perfectly free, with no ex- 
plosion taking place. The moment the lever is let 
down again, the motor starts its usual work. This 
compression release is operated by the left foot. 
On the steering wheel is a spark cutout. The 
spark advance is on a right-foot pedal. Coll and 
battery ignition. 

Chassis. — The running gear has for diagonal 
struts steel tubing pinned and brazed in sockets. 
The horizontal members connecting the hubs of 
the three wheels are of spruce. The axle of the 
two rear wheels is of angle steel. 

The wheels are of Weaver make, 20 in. rear 
and 16 in. front, fitted with Hartford aviator tires 



The fiiselaye is made up of spruce, with steel 
sockets, stayed with piano wire. In the next ma- 
chine, which is to l)e finished by Sept. 1, this will 
be built of ash and stayed with Roebling aviator 
cord. The aviators seat is suspended by piano 
wire. 

The Month Past at Mineola. 

Nearly every day during the past month flights 
have been made by Harmon, Baldwin, Russell and 
.Toe Seymour. .7. .T. Frisbie on two Sundays made 
hot air balloon ascents and parachute drops. 

MANY .M.\CIII.\E.S ON THE GROUND. 

Dr. William Greene will soon have one of his 
biplanes down at the Aeronautical Society's shed 
for flights. 

The machines in the Aero Club sheds are : 
Clifford B. Harmon (Farman). Capt. T. S. Bald- 
win (Baldwin), W. L. Fairchild (own monoplane, 
building), H. S. Harkness (Antoinette), and Philip 
W. Wilcox (Farman-type) . At the .\eronautical 
Society sheds are : Miss E. L. Todd ( biplane, not 
yet tried), W. Diefenbach (making). Frank Van 
Anden's light Farman-type with Ilarriman engine. 
Geo. Godley (imitation Curtiss, making). Dr. 11. W. 
Walden (monoplane with Anzani motor, recently 
damaged at trial), M. P. Talmage (making Cur- 
tiss-type), G. E. De Long (Shneider make of Cui-*- 
tiss type, with Elbrid'ge engine), .las. Murgatroyd 
(biplane own design, with two Adams-Farwell 
motors operating individual propellers, not yet 
tried), George Russell (ono Curtiss with Harriman 
engine and one copy, former making almost daily- 
flights), Elmer Bu)'lingame (own design monoplane, 
Harriman engine, not yet tried), Louis Rosenbaum 
(monoplane, owner's design, not yet finished), 
Edwards & Edick (small copy of Curtiss, well built, 
own make of engine), Paul Kilduchevsky (mono- 
plane, owner's design, making). 

The Society has added an extension .30 by 138 
ft. to its already large shed to accommodate some 
of the machines which have been housed under 
tents. 

AVI.VTOR.S .SHARE PROFITS IN GATE RECEIPTS. 

Some time ago the owners, a real estate con- 
cern, of the lands over which the flights are 
made, built a fence on three sides and began 
charging the public admission to a grandstand and 
the field. On Aug. 13 there was established a 
system of "points." each machine making an ap- 
pearance on tho field earning 1 point, a short 
jump a certain number, length of flight is re- 
warded, etc. The aviators share in profits ac- 
cording to the points earned. The two aeronaut- 
ical organizations have nothing to do with the 
financial end of the enterprise, merely leasing shed 
ground and privilege of flight over the other lands. 
Each Saturday and Sunday large crowds view the 
flights of Harmon, Baldwin, Russell, Seymour, 
etc. Mr. Harmon objects to accepting mioney prizes 
and takes a cup or trophy instead.

FLIGHT PROGRESS OVER THE COUNTRY 



Flights With Burgess Aeroplane. 

William Hilliard lias been making' a constant 
succession of flights with one of the Burgess Co. 
& Curtiss machines at Plum Island. Mass., having 
flown on one da.v alone :.'."i times without breaking 
even a rib or skid. The company's energies are 
being devoted to the :Model C "Flying Fish" which 
is to have wheels as well as skids and to be 
driven by a Clement-Bayard .'JO h. p. motor. The 
company has hitherto employed two different tyjies 
of propellers designed by A. M. Herring, two de- 
signed by Mr. Pflitzner and two Cliauviere. A new 
propeller is being developed to have tlie good 
point.g of these without the defects. This will be 
of the 2-bladed type with uniform i)itch and as 
symmetrical as the highest efficiency will permit. 
The general design will be adapted to different 
diameters, the standard diameter for light ma- 



Harvard Biplane Flies. 

The Harvard Aeronautical Society, numbering 
400 members, lays claim to having tlie liglitest 
biplane in the world, its weight being but 1G5 
pounds, including wheels, but without engine. 

The riding surface is 200 so. ft. and the con- 
trol surface 35 sq. ft. Equipped with disappear- 
ing wheels and offset surfaces, it is constructed of 
hollowed and laminated air-dried spruce without 
l)olts, screws or nails. The after cross-piece is on 
top of ribs, while the fabric is underneath the 
ribs. 

The machine, which was built by S. L. Saunders 
and certain Harvard students, has made several 
12r)-yard flights within Soldiers" Field, fitted with 
a regular Cameron 4-cylinder, air-cooled automo- 
bile engine, at a lieight of 8 or 10 ft. However,

The control device is novel in the "Harvard I." 
I There are two elevators in front, each operated 
by separate levers at the right and left hand of 
the aviator. In ascending or descending, both are 
moved to the same extent, but one or the other 
is moved individually to maintain lateral equilib- 
rium. The levers lock automatically on being 
released. The vertical rudder is regulated by the 
operator's foot. The motor and direct-connected 
propeller is swung in a revolving cradle, with the 
axis of support jmssing through both the center 
of gravity and the line of thrust of the motor. 
By a simple movement of eitlier hand or foot the 
operator can adjust the thrust angle at will. The 
device is self-locking and free from vibration. The 
norm of the line of thrust passes through the aero- 
plane's center of pressure. Detachable wheels 
eciuipped with spring shock absorbers are attached 
to the skids.

IN THE AERIAL MARKET PLACE

much if you ivould specify in writing advertisers 
that you saw the ad. in AERONAUTICS. This

i/ourselves. 



Detroit Aero. ConstruLtion Co. Motor. 

1"he Detroit AeroiiMutie Construction Co. of De- 
troit, Micli., realizing some time ago ttiat tlie 
present type of automobile or marine motor was 
entirely too large, heavy and cumbersome for avia- 
tion work, set about to build the smallest, light- 
est and most effective power plant which could 
possibly be constructed. Its :;U-4U h. p. motor 
weighs well inside of 175 pounds, including a 
double ignition system, cnrlmretor and propeller. 

In order to secure efficient service, ball bearings 
are used wherever the same are at all practicable 
or applicable. 

With the exception of the cylinders, pistons and 
crank shafts, the entire motor is built of aluminum, 
including the Schebler carburetor, which is being 
made especially for this motor, thus reducing the 
motor to the very minimum of weight without 
sacrificing strength in any way. 

The company has no hesitancy in saying that, 
in so far as size is concerned, it is building the 
most compact motor, for the power developed, in 
the world, the ;-J0-40 h. p. motor occupying but 
about 18 by 19 in. of space over all. 

The cylinders on all motors are cast en hlac. 
The crank shafts are cut out of solid blocks of 
chrome nickel steel, and are carried on two large 
Hess-Bright ball bearings. All rotary parts are 
thoroughly balanced and in every way made as 
light as possible, without sacrificing strength for 
lightness. The intake, as well as the exhaust 
valves, are made especially largo, to insure perfect 
intake of fuel, as well as absolute scavenging of 
cylinders. In the construction of the intake valves 
and manifold, the company has gotten away from 
the adopted form, and has adopted a system of its 
own, which is unique in so far as compactness 
and simplicity are concerned. The exhaust is 
effected by a peculiar cam operation, giving an 
easy rotary movement, combined with quick ac- 
tion, and is "fool-proof." 

The company has also gotten away from the 
ordinary in its oiling system, which consists of a 
very siiiall rotary gear pump built in the crank 
case, so as to be easily accessible in case a repair 
should be necessary. This forces the oil to all 
cylinder and connecting-rod bearings. The oil 
being pumped from a sub-base to the cylinders 
and to the crank case makes a splash system, a 
lever overflow pipe to the sub-base taking care of 
all excess oil. 

Years of experience in building motors for rac- 
ing boats has taught the company that in order 
to secure absolute ignition its motor must be 
equipped with a double ignition system. This 
system consists of a Bosch magneto and of a 
primary and secondary distributer with a single 
coil, and it is the claim of the company that it 
has the only perfect ignition system in present use. 

The company states : "That tlie motors built 
by this company are a success is proven by the 
many orders which it has received from persons 
who have spent much time and money in experi- 
menting with other motors, and who have dis- 
carded the same for the Detroit motor, and have 
found perfect success with it. References as to 
successful users of this motor will be gladly fur- 
nished by the company on application." 

The company is now making arrangements for 
the building of a larger factory, in order to 
enable it to take care of its rapidly increasing 
business. Orders for more of the latest improved 
machines have already been placed, and negotia- 
tions for the building are now in progress. The 




Detroit Aero 
Construction 
Co. Motor 



company is always glad to see prospective cus- 
tomers ' and have them examine the plant and 
the motor. All motors are furnished with either 
aluminum flywheels or laminated wood propellers. 

Hall-Scott Aeronautical Motor. 

Two types of aerial motors of light weight are 
offered by the Hall-Scott Motor Car Co. of San 
Francisco, Cal.. this concern having already deliv- 
ered a number of them to western aviators. 

One of the interesting facts about the success- 
ful flight of the Wiseman-Peters aeroplane at 
Petaluma was the use of a Hall-Scott eight- 
cylinder, 60 h. p. motor. W Hall, the designer, 
is best known as an automobile man, being well 
known locally as the builder of the Comet auto- 
mobile, which made all kinds of records on local 
California tracks for two seasons. 

These engines are both of the four-cycle type, 
water-cooled : a four-cylinder, .30> h. p. and an 
eight-cylinder 60 h. p., both having cylinders 
measuring 4 in. bore and 4 in. stroke, and with 
the exception of the crank shaft and crank cases 
all the parts on both types of motors being inter- 
changeable. 

The cylinder walls, pistons and heads are made 
of a special cast iron. The valves, of nickel steel, 
are seated directly in the removable heads and 
ojierated by push rods and rocker arms. The water 
jackets are of spun copper, a by-pass between 
the jacket and cylinder head being used as a 
preventative of any leakage into the cylinders. 

The cam shafts are located in the crank cases, 
which are of the strongest known aluminum al- 
loy. The crank shafts and connecting rods are 
machined from hand forgings of a low carbon 
machine steel, which it is claimed is best adapted 
to use where a propeller is employed, bored and 
milled and ground accurately to size. Main and 
connecting rod bearings are of larger size than 
ordinarily used, being 1 % in. in diameter. 

The crank cases are split, the bottom oil cases

The Detroit Rotary Motcr. 

Till' .Michigan Airshiji Co. has been formed in 
Detroit. Mich., to make and distribute a new ro- 
tary en'rine. called the ■■Rotaero.'" It is claimed 
b.v the makers that in tliis motor many of the aims 
of the engine designer, great jjower with little 
weight, long life, simplicity, accessibility, freedom 
from repairs, etc.. have been accomplished. 

I1ESCRIPTIO.V BY FREDERICK WEIXBrui:. 

The engine is a 1-cylinder in jirinciple, which 



has been divided into two i)erfectly l)alauced units, 
and the different working phases of the cycle, as 
charging, compressing, e>iilosion and expansion, 
occur in both units exactly at the same time but 
in opjiosite directions. This relieves the center of 
the engine from any bending strain under normal 
conditions. 

Adverse criticisms have been made against the 
multiple type of rotary engine for the simple 
reason that it requires a man of thorough technical 
knowledge to locate ignition troubles. In the 
revolving 1-cylinder t.vpe the difflcultv of locating 
the ignition troubles of the multiple cylinder ro- 
tary tyiie is being eliminated, as both sparks must 
occur simultaneously in the same place, which is 
not the case in a multiple cylinder type of engine. 

This engine has been designed in accordance 
with the 2-cycle principle, because a 2-cycle en- 
gine gives more power for a given weight than 
the 4-cycle, and eliminates in the jiresent design 
the intake valves entirely, and simplifies the elec- 
trical or mechanical timing arrangement to a great 
extent. 

In the present design the .so-called, "straight- 
line" clearance has been introduced which is even 
of a greater volumetric efficiency than the 4-cycle 
principle, inasmuch as there is 'no non-scavenging 
space above the piston in which the burnt gases 
can possibly remain, which is often the case in 
the imperfectly designed valveless 2-cycle engines. 
The new^ charare, by aid of the crank case com- 
pression, fills the cylinder through the by-pass on 
the very lowest point and leaves through the 
head valves after the exnansion stroke, and inas- 
much as carburetor intake and exhaust ports are 
located in a radial direction to each other, the 
centrifugal force jilays a very prominent role in 
the process of charging and discharsing, helping 
to throw the charge into the crank case, transfer- 
ring the same from there into the cylinder and 
after the expansion stroke into the air. 

The engine may be mounted hanging from one 
ben ring like the French (Jnonie motor, or it can

preferably be located between two bearings while 
the propeller swings outside the front bearing. 

The pistons describe a true circle around the 
wrist pins and form, during a lialf revolution of 
the engine, a vacuum in the cranio case, drawing 
the g-as and oil mixture through the hollow crank 
shaft and a mechanically operated poppet valve 
into the crank case wliere it is compressed during 
the next half revolution, then entering the cylin- 
ders by means of the l)y-pass, filling same. A 
short time before the head of the piston clears 
the by-pass, the exhaust valve is opened mechani- 
cally and the burned gas rushes out, driven by 
its "own pressure, mostly before the piston head 
reaches the bv-pass opening- and as the exhaust 
valve is still open at this moment, the new charge 
entering the piston gets a chance to assist in 
driving the remainder of the burnt gas out. 

Touching on the constructional side of this 
new aeronautical power plant, the different parts 
of the en<4in(^ are machined to fit within one- 
thousandth of an inch, and are made on the in- 
terchangealile plan through the use of precision 
instruments and fixtures. The crank case is made 
of aluminum, and is cast in one piece. Cylinders 
are made from cast iron machined all over. The 
pistons from the same grade of cast iron and 
contains three rings, of which two are above 
and one below the wristpin. The crank shaft is 
double throw, and bored out to reduce weight and 
to admit the gas(>s. The exhaust valve is located 



aid of all scientific means, and the results of 
these tests will be published in a subsequent 
issue. 

Church Aeroplane Co. Busy. 

The Church Aeroplane Co. has completed a 
Bleriot, cross-cliannel type, for Cohan & Harris, 
theatrical managers, to be used this fall in the 
new play, called the "Aviator." 

A biplane is also building for Kramer, the 
former l)icycle champion. 

The World has bought an exact model of the 
Curtiss .\lbany-Xew York flyer, built to scale 2 in. 
to the foot, and all details are carried out very 
minutely. Seven of the principal type models have 
been shipped to Revere Beach. These were built 
to order for the Suffolk Amusement Co., and are 
on exhibition in connection with a daily balloon 
ascension. 

The Church company recently moved to new

room enough to build four macliincs at once.

in tlie head of the cylinder and is made from 
(he same grade of ca.st iron as the latter and is 
of sufficient area to empty the cylinder in mini- 
mum time. The magneto is driven positively at 
crank shaft speed which insures an easy starting 
of the engine direct, without the aid of battery 
ignition. The engine is hold together by means 
of two tension bars terminating at each end in a 
valve cage retainer in which the valve is seated 
and held to the cylinder and with the same is 
held to the cranlv case. It is natural that the 
cvlinder valves, etc.. exert an enormous pressure 
through the action of the centrifugal force, and 
Ivce]) the valves seated tight. Consequently in this 
way the cylinder is in compression instead of in- 
tention and as the tension bars are of sufficient 
size to take care of the pressure at a high speed 
with an ample factor of safety, there is no danger 
whatever for the jjarts to become loose or to be 
thrown off. American-made annular ball bearings 
have been used as main bearings. The connecting 
rod bearings are made from best white brass. 
The lubrication system employed is the spraying- 
system by which "the nil is drawn into the crank 
case in form of a flne spray, oiling in this way 
all internal working parts. The testing experi- 
ments of tliis (>ngine have not been completed, at 
the time of going to press. However, arrange 
ments have been made with one of the foremost 
universities to have this engine tested with the

llie writer in the l:>vi(ii1Uii- Ai/(Ciiciiii tiui)i)lcin<uil

general subject of ortliogonal flight was illus 
Hated and discussed by tlie writer in the above 
l)ublications of Aug. 11. 1894; Jan. 30, 190i4. and 
the Klectriciil World of June 20, 1896. 

As a replica or close copy of tlie device here- 
with illustrated is now under construction, it is 
thought a brii'f stati'oieur of the characteristics 
we will doubtless establish may be of interest to 
readers of the fast developing aerial art, and they 
are certainly more numerous than when the ar- 
ticles referred to were published. This device is 
especially designed for warships and kindred pur 
poses. For the army, for explorations or for pre- 
liminary surveys, etc., it may be dismantled for 
compact transport. Tlie design for' general com- 
mercial usage weighs less and ajjpears somewhat 
different in aspect, as the aviators are seated ard 
other expedients availed of for maneuvering, whicli 
will be described later. It may be flown from any 
l)lace without a runway or other .starting arrange- 
111(11 Is. and will alight at any unobstructed point 
where there is space for it to stand upon. II is 
intended for use as a ship's adjunct and flown 
from its deck. It may be flown from land ; it 
may be flown from water. It will rest upon a 
sea of considerable roughness, when i^roperly 
equipped therefor, and will rise therefrom with 
greater efficiency (less power) than from the land, 
because of lessened weight, due to parfial sub- 
mergence, and greater facility, because of the ab- 
sence of drag due to vertical tilt as distingMished 
from forced translation through water and the 
consequent skin frictional resistance of any sucli 
attempts with monoplanes, biplanes or triijlanes. 

The modus operandi of the translation and di- 
rection of this machine is, curiously enough, the 
same physical principle that lends itself to Ihi- 
locomotion of land animals in- walking or run- 
ning—viz., the center of gravity displacement. 
That is to say, when in suspension the center of 
gravity of the machine is determined bv the posi- 
tion of the load relative to the axlS; and the load 
is the operators, who are free to move together or 
separately about and around the axis or support- 
ing pedestal of the machine. (Jbviously, then, (ho 
raacliine is caieened and the cant or tilt of die 
axis to the points of the compass determines the 
direction of translation through the air, and it 
takes little cant to make liigh speed. It is easily 
shown that gyroscopic action will not interfere 
appreciably in the operation of handling this 
machine. The action of the gyroscope is oniy 
apparent when it is subjected to quU'lc movements, 
or sudden precession, from its plane of revolution. 
The heavy wheel? of a vehicle rounding a street 
corner, or the driving wheels of ■x loGomotivo 
rounding a cu've, have a decided gyroscopic Vend- 
ettey : but we kijo.v it is negligible, duj principaiJy 
to comparative moderate rotative speed and the 
Oiadual changing of their planes of revolution. 

Instead of so-called automatic stability, it is 
apparent that this machine has inherent stability 
like a boat ; and this can be made adjustable liy 
telescopic arrangement. Quite the same as a boat 
can l)e made variably stable l)y the weight and 
|H)sition of the load relative to the water line 
or plane of buoyancy. Hence th(> long training to 
acquire specialized skill is not necessary. The 
mental and ordinary requirements of a competent 
auto driver would be all-sufticient Wind resist- 
ance is minimized Ity compactness, which, combined 
with weight, insures precision of movement when 
in the air. With proper equii)ment its shop cost 
would lie moderate. 

I have shown how the machine is directed by 
the center of gravity displacement. Other maneuv- 
ers, such as jockeying to attain altitude, are 
effected the same as we meet the up and down 
grades with niir automobiles and other vehicles by 



increasing or decreasing the motive power. H 
utilizing the two expedients described, every met 
tionable evolution can be made in the air, fro 
a stand-still or stationary suspension — even spii 
ning around like a top in either direction in su 
pension — to a straight, curved or spiral path i 




or ('i)wn ai any angle to the iKiri/.ou — or vc 
tically — without the imiiedimeuta of tail, win 
rudder, aileron or complicated mechanism, or tl 
addition of a pound weight. 

"The real future of flying, or rather the pra 
tical solution of the problem of the air." M 
Chanute thinks, "will come with the explosi( 
motor turned into a 'sustention' engine.'' follow 
ing a statement that he does not foresee mu( 
utility for aviation carried on along the preset 
lines. Doubtless the heart and key to all typi 
of flying apparatus lie in the motive power, an 
all types of engine will needs lie adapted to tl 
different types of machines, of which at the pre 
ent time there are only two in evidence of tl 
heavier-than-air sort. ]ioul)tless also the greate. 
rteld for broadening and perfecting the aerial a 
is for the theorists to get busy and evolve a r 
liable fundamental power principle, or constnictioi 
involving no reciprocating parts like the electr 
motor, for instance, which, unfortunately, is not 
prime mover. Then we will begin to see dayligh 
I know of at least two of some promise. Barrin 
this desideratum, we must do the best we can wit 
existing systems. 

The original arrangement of the two-cycle ei 
gine shown in the publication first referred to, c 
radially arranged revolving cylinders incorporate 
at the hub. has been introdticed substantially o 
the same lines by the American Adams-I'arwe 
and the Frencli (inome companies for aeronautic 
work. Tliese rotatory engines have features c 
air-coolin.g and liglitness which are very stron 
factors and are likely to be controlling for soni ; 
tyi)es of flying machines. In, the illustration heri 
with 1 have eight two-cycle cylinders groupe 
aniuiid and parallel to the axis. The eight cy ; 
inders act as a unit, of course, through tin' trait.- 
mission. This makes a good arrangement in som , 
resjiects. but. for certain mechanical reasons, tit 
prime mover of the machine under construction i 
arranged as three twin-cylinders acting as a uni 
through a reverse motion differential speed tran? 
mission of nickel-stei>l spur and internal geai> 
Th(> maximum power developed is 90 horse; tli 
normal power is 75 horse for the three engines- 
i. e., six cylinders of 12% horsepower each. Th i 
engine has special features for clearing the cyl| 
inder and purifying the mixture for perfect coiii I 
bustion. Ir weighs about 202 pounds, or 2.' \ 
pounds to the horsepower. I have aimed in tb j 
jiresent construction to make a full-sized machini'[ 
which can be considerably modified without rooori 
struction for experimental data of which there i' 
practically none extant. With that end in view

the diameter over all may be varied from 12 to IT 
ft. It is believed, however, that with hish power 
and efficient screw action diameters of around IL' 
ft. will be sufficient for the practical working of 
Uotaplanes of medium-load capacity. 

The illustration .■-■hows superimposed screw- 
blades supported by a tubular double-rim tangent 
wire-spoke wheel. This (rotary) biplane arrange- 
incut has not been tested out by the writer, but 
I lie machine under construction vv^ill determine the 
advantage or otherwise of this feature. The gaso- 
line and lubricant are contained in the 1/32-in. 
sheet-steel pedestal. The cavbm-etor hns been 
changed from near the base to near the engine, 
so it will not be interfered with when alighting 
on the water. The total weight of the machine for 
two persons is about 400 pounds. 

The word aeroplane, or monoplane, or biplane, 
(ir triplane, applied to the respective examples of 
present-day flyers, is a misnomer, because the sup- 
porting surfaces of all machines up to the lU'esent 
rime have l)een aerocurves exclusively — something 
(juite different. In view, however, of the hold 
these words seem to have on the popular imagina- 
tion. I will venture to name the type of the 
machine illustrated herewith a rotary aeroplane or 
Rotaplane.

A LETTER FKUM SOUTH AFRICA. 

.Toe W. Naude, Graaff Reinet, Cape Colony, is 
industriously working out some novel features in 
flying machines, not to mention an aeroplane that 
uses a small motor for starting only and a heli- 
copter tombined with a bi])lane glider. The nov- 
ellies cover lateral automatic stability, aero lirake, 
means f(u- changing angle of incidence main planes 
(luring flight, shock-alisoi-bing device and mono- 
wheel and skid combination, reversilile |)ropeller, 
vertical and horizontal rudders liotli lure and aft.

wrk;ht and fuirnss loijrii.ir.Kir m ch.ni'kol. 

Item- Sirs: — 

I would like to give my idea of llu' dillerence 
between the Wright and fhe Curtiss e(|Mlil)i-iuni 
control. 

When th(> Wright machine tips lo one side, the 
low side is warped so as to increase its angle of 
incidence. In other words, the lift of the low 
side is increased and that of the high side de- 



decreased. The low side, having the greater angle 
of incidence, has more drift ; this would make the 
machine travel in a circle with the low side to- 
ward the center, this tendency is overcome by 
manipulating the rudders. 

The ailerons in the Curtiss machine are an- 
alogous to elevator rudders. Then when this ma- 
chine tips to one side, the low side is steered up 
and the high side is steered down by manipulating 
the ailerons or wing tips. In a Curtiss machine 
flying there is no very noticeable movement in 
these ailerons, which goes to show that they move 
through very small angles. Since these surfaces 
are flat their drift at small angles is very slight, 
so that any diffi i-'nce of resistance ( li there is 
any) at the wing tips is so slight as to be imma- 
terial, therefore the machine does not deviate from 
its course. 

E. S. Locke,

HAS NEW STABILITY DEVICE. 

To the Editor:^ 

There has been so much talk of late re- 
garding the Wright patent and the danger of 
their monopolizing and hindering the advance- 
ment of the art that I take this opportunity of 
showing a few different improvements designed 
to be used on any make or style of aeroplane and 
render flying safer and soaring more possible. 

My O'b.jective point has always been an in- 
stantaneous control under all circumstances and 
conditions, all possible accidents considered and 
])rovided for. in my imiiroved auxiliary plane 
system, I Ihink I have accomplished all this and 
more. 

Pig. T is a plan view of a machine with im- 
orovcd horizontal or elevating rudders, with which 
it is possible to steer up or down and to right 
or left and balance the machine simultaneously 
with one lever. The dotted line C. on main plane 
.V, shows end of ribs and beginning of extremely 
flexible portion as shown in Fig. VI. .\ is rib: B is 
beam: C. rear end of rib : D. flexible portion of 
rib which in itself is an eoualizer of pressure 
but may lie warped down c>n tbr> low side of ma- 
chine eitlun- manually or nutomatically. 

l'"ig. \ shows two vertically disqio.sed screens 
operatinff transversely of the machine, designed 
as an em-^rgency or auxiliary lateral steering gear 
with which vertical cells or jjartitions must be 
used to prevent side drift as in A'oisin type or 
may be used to stop machine when both are 
pulled out simultaneously. In construction they 
are simple and are practically the same as the 
ordinar.v roller curtain or window shade without 
rachets. The drawing represents a front view of 
both ends of machine: A. main jilanes : B, ad.iust- 
able screens ; C. cords : I), wire in front of which 
the screens operate, thereby allowing the action of 
the springs on screen, which would be prevented 
liy the pressure otherwise : the idea being to 
l)resent a desired amount of surface on the side 
corresnonding to the dir(>ctlon (I. e. rieht or left) 
in whi'-h the machine Is to be steered, retarding 
one side of machine and permitting the other side 
The longitudinal action front and rear is simul- 
taneous. There is no transverse nction of rear 
rudders except for emergencies. The advanta'.'es 
to revolve around to any position desired, might 
also be used to restore enuillbriuni to a certain 
extent liy presenting surface on fhe high side of 
ninchin(\

It is proposed to keen on file all publications 
of interest to the members of the Council and 
Secretaries of the various organizations are re- 
nuested to send such publications as will be of 
interest in this connection. 



,\t a luncheon arranged Iiy Clifford B. Harmon 
and Gaae E. Tarbell. before the latter"s falling-out 
with the -Vero Club, at which affair a number of 
members of the Club and the .Veronautical Society 
were present, it was decided to ask both organ- 
izations to appoint a representative to meet and 
endeavor to arrive at an vniderstanding with re- 
sard to the friction which the Club insists exists 
between it. as parent, and the Society, as offsprintr. 
It was suggested at the luncheon that the ri^pre- 
sentatives be Mr. Harmon for the Clul) and Hudson 
Mavim for the Society. The Club, however, ap- 
pointed W. W. Millei-. an attorney, and the Society 
deli>gated Thomas .V. Hill, also a lawyer and a 
"rank insurgent" in the Club. jSIr. Harmon was 
thought l)y the Club not to be eligible to the honor, 
as he is also a member of the Societ.v. though sort 
of a non-resident. Xo conference has been held, no 
ofhcinl cemmunications have passed, and the idea 
is thought to have succumbed to dry rot. 

Whnt lias become of the Aero Club of Phila- 
delphia? Letters addressed to them are re- 
turned by the post office. The same is true 
of the Aero Club of the Northwest, St. Paul.

Corrected Figures New York-Philadelphia 
Flight. 

T'nfortunately for the standing of one of the 
first great cross-country flights in tlie States, that 
of Charles K. Hamilton from Governor's Island 
to Philadelphia and return, it seems evident that 
the official timers employed by the Xew York 
Times have made an error on the return portion 
from South Amhoy to Governor's Island. The 
distances which were given out by that iiaper 
were far from correct, as we mentioned at the 
time. 

T'sing the flying time of the Times, Hamilton 
made *57.0fi miles per hour from South Amboy 
to Govei-nor's Island, doing the distance of 2'l.lOTt 
miles in 2.'> minutes. Xo doubt this time should 
have been :!.'{ minutes, a speed of 40.10 m. ji. h. 
In view of the speed made going to I'hiladi'liihia. 
without stop, when everytbin.g was working well. 
4.". 20 m. p. h.. it does not seem prolinble that the 
great increase was made on the second half of the 
return .iourney, when the engine was even miss- 
ing fire. 

It is not intended to detract one iota from the 
achievement. l)ut merely to follow out our inten- 
tion of having nothing in the magazine but that 
which is accurate, when accuracy is possible to be 
attained. .

I 1 he Call Aviation hngine 

I ^^^==^^^^ IS ^^^^^=^^^= 

T 1st. .4 Four Cycle Engine. Tlie type used on 09% of all automobiles and motorcyles. The 

T type used by all prominent aviators here and abroad, and holding all aviation records. 

T -^nd. ,-1 Water Caoled Engine. Tlie only kind that can be dependi-d upon for extended runs 

^ without danger of overheating. Our spiral water jacket, together with piston pump circulation is 

■!• the most perfect cooling sys em yet devised. 

i|i 3rd. An Oiipo.scd Vylinder Engine. The construction I'onceded by gas engine authorities to 

the tlie ne;»rest vihrationless type. By all odds the construction best adapted for aviation |)urpo«es. 
till. -4 Silent Engine. The only engine yet designed for aviation having both main and 
auxiliary ports silenced. Hence the only aviation engine adapted for permanent use, or for other 
than merely exhibition purposes. 

fitli. A "Fool-Proof" Engine. The utmost simplicity of construction, small number of 
cvUnders, together with its being of the usual Four Cycle type, enables any automobile chauffeur to 
sjt and run it, not one in fifty of whom have any experience with Two Cycle, Revolving Cylinder, 
or V-sha|)ed mult'ple cylinder engines. 

tith. .4 Thoroughly Dependable Engine. Our Magnalium outer casing for cylinders and 
cvliiider he ids permits of a remarkably strong construction with minimum weight : while our Vana- 
dium (Ircy Iron Cylinder and cylinder lu'ad linings, piston heads, valve cages, valve seats, etc., is the 
only dependable nnti-rial for these parts. 

7tli. ,1 Superbly Heantifnl Engine. The entire dc^ign is thoroughly artistic; while all ex- 
posed puts not constiucted of Magiidium— a shining non-con odible metal — -are nickel plated, the 
whole surface being polislied to a mirror finish. 

stli. ,4 PhenonieiKdly Pon-crfnl Engine. This result is secured by the use of a comparatively 
small number of cylinders of generous projiortions, as distinguished from a multiplicity of cylinders 
with their numerous parts and beirings. and consequent friction, and liabdity to derangement. 

9t!i. ,4)! E.vceptioruilly Economical Engine. It is a matter of common notoriety among gas 
engineers that economy of fuel, as comp ired with power developed, is secured by large cylinders, 
few in number, rather than by a multiplicity of small cylinders— a consideration of paramount im- 
portance in aviation. 

lOth. .4 Moderate Priced Engine. Wliile the material and workmanship of this engine is even 
superior to the very expensive foreign makes, and not to be classed wiili the cheaj) engines flooding 
the market, yet our aim has been to furnish avi itors with a moderate firitcd engine, cheaper than 
could be produced by themselves, except in large numbers, and with an cxpiiisive shop and foundry 
equipment. 

Other Aviation Engines possess a few of these advantages. This is the only engine that combines them all. 
MODEL E-1 : Two Cylinder; 50 Horsepower, weight, 150 lbs. - Price $1,000 
MODEL E-2: Four Cylinder; 100 Horsepower, weight, 250 lbs. - Price $1,700

AN AMERICAN BALLOON TRIP OVER ROME 

Some Noted Events and Thrilling Experi- 
ences in Balloon Voyages in All Parts 
of the World, Written Especially for 
"Aeronautics."* 

By Rufus G. Wells 



I.\ 1870, aftiT winning a balloon race in Loudon 
with an English aeronaut, I went to I'aris to 
offer my services to the new Republic. There 
I was employed l)y the Defense Nationale to 
construct a balloou for taking (ieneral Bazainr 
with his officers out of Metz and carrying- them 
over the German army and landing them in France. 
From silk furnished by the government, I made a 
balloon two hundred feet in length. About thi' 
time that this was completed, the largest balloon 
at the time ever constructed, we were disai)i)ointed 
liy ihe surrender of Metz by General Bazaine. 

A most interesting e.\i)erience in my ballooninj; 
took i)lace (luring the >Vorld's Fair at Paris in 
1S81I. 1 madi' an ascension in company with Wil- 
liam .T. Hammer, electrical engineer and director 
of Thomas A. Edison's exhibit at the Exposition, 
and Dr. A. Lawrence Rotch, director of the Blue 
Hill Observatory at Boston. Many interesting ex- 
periments, both electrical and astronomical, were 
made on the voyage. The balloon was in the air 
about four hours, traveling on an average twenty 
miles an. hour. 

On one occasion I made an ascension from a 
beautiful garden in Copenhagen. I was carried by 
the wind over to Sweden and landed in the sea, 
where I was rescued by men in boats. 

On a visit to Italy I made an ascent at Milan 
during a festival. The balloon rose to the height 
of three miles, and I then made a descent in a 
parachute, to the grent astonishment of the multi- 
tndc. lieing the first (exhibition of the kind they 
had ever witnessed. 

From Italy I went to Constantinople, where 1 
madi' an ascent over city, obtaining a magnificent 
view of the palaces, temples and mosques. On my 
des -cnt I was well paid by the Sultan, who also 
gav(> me some rich and splendid gifts. 

On an extensive tour in India I made many as 
censions in the most celebrated cities — Bombay, 
Delhi, Agra, Lucknow and Calcutta. The Maha- 
rajah of Cochin gave me a bag of money and took 
a (iiamond ring from his finger and made me a 
pres(>nt of il. At Akyob, in Burmab, I made an 
ascension and was carried out over the sea. On 
being rescued by mcni In a boat and taken to land 
the people gathered around me, believing that one 
of their gods had appeared amongst them. 

I>uring a summer spent in the island of .Tava 
I made the first balloon ascension in Batavia that 
had ever been witnessed there. The balloon passed 
up through a cloud and the people thought it was 
the last they would ever see of me. I went off 
about lOO miles and landed on a rich tea and 
coffee estate, to the great astonishment of the 
natives at work there. 

In South .\merica I made ascensions at Lima. 
I'eru : at Kio .laneiro and at Buenos Aires. .Vt the 
latter placi^ I descended in the La Plata River. On 
throwing out Itallast the balloon rose so rapidly 
that the sun which had just gone down was seen 
rising about the horizon, in the west instead of 
the east. 

On different visits to Mexico I made sixty ascen- 
sions, and received full remuneration and utmost 
courtesy from the people wherever I went. I was 
the first aeronaut to make a parachute descent in 
rhiit country. 

*Kufus G. Wells, up to his death the oldest liv- 
ing .\merican aeronaut, di(>d on August ."^d at his 
home in St. Louis, aged 80 years, while sitting 
in his chair, stricken with apoplexy. An account 
of Mr. Wells' experiences in ballooning was writ- 
ten by him for .\eron'autics in the fall of lOO.S. 
His most interesting story will be found in this 
issue. 




Rufus G. Weils 
W.\.\Tf:D TO CROSS THE ATL.\NTIC. 

It was my desire to cross the Atlantic with an 
immense airship seven thousand feet in length and 
two hundred feet in diameter, inflated with hot 
air, and enough fuel to burn and provisions to last 
on the way. not only to cross the ocean, but to 
go around the world with some brave companions. 
I ought to have carried out my project long ago, 
and to have l)een the first one to reach the North 
and South Poles with a gigantic dirigible. If 
wealthy men would assist, immense airships could 
be made to carry a hundred persons with safety to 
any part of the world. 

.\11 governments should use great airships in 
war and to visit all parts of the earth. I was 
very much pleased to carry the Stars and Stripes 
higher over Rome and other cities than any other 
person has ever waved them, 

THE AMERICAN FLAG OVER ROME. 

The Pope and Governor of Rome said I must 
not wave our flag over Rome — but I did wave 
it in spite of them, and they said I could not 
make another ascent from Rome.

PROPELLER DESIGN AND CONSTRUCTION 



By Spencer Heath, 

OF THE AMERICAN PROPELLER CO. 



SOME remarkable results are lieing attained by 
tb(> American Propeller Co. from their 
"I'aragon" propellers, according to the re- 
port of the Emerson Engine Co.. of Alexan- 
dria, Va., which is putting a new 0-c,ylinder 
2-cycle aeronautical engine on the market. 

A "Paragon" propeller tested by them on one 
of their engines which they sold recently to 
Dr. W. W. Christmas of Washington, D. C. for 
his new biplane, lied Bird, now being experimented 
with at College Park, Md., gave the extraordinary 




thrust of 4.">(> pounds at a speed of I.IOO r.p.m. 
The propeller was designed specially for the par- 
ticular surface-weight ratio and other properties 
of the Christmas machine and the speed and 
power of the engine, the aim of the designers 
being to adapt tlie actual flying thrust of the 
propeller to the head resistance of the machine 
at its calculated speed of travel and that the 
propeller shall have the least disturbing effect 
upon the air wlien the engine is running at its 
most efficient speed of about 1,100 r.p.m. 

The propeller in question is 8 ft. in diameter, 
by a pitch varying from 4% ft. to 5 ft. at different 
parts of the blade. The material is all edge- 
grained white siiruce with five laminations in each 
blade, all ol' the pieces being spliced or scarfed 



together at the hub in the manner characteristic 
of the •'Paragon" propellers and all the glued 
joints throughout the blades being made doubly 
secure by numerous birch dowels regularly spaced. 
The hubs are faced with hard maple. The weight 
is 10% pounds. 

It might readily be assumed from the great 
standing thrust yielded by the "Paragon" pro- 
pelleis tliat they are designed particularly with 
this I'csult in view, but that is not the case, the 
standing thrust being merely incidental to 
desigTi for giving tlirust at speed. 

The main feature of the American Propeller 
Co.'s work is to furnish propellers designed in- 
telligently and scientifically for each individual 
case, believing that no standard design can be 
evolved while there is such wide diversity in 
tiying machine construction. This diversity is 
shown in the extreme variations in surface-weight 
ratio, from about two to perhaps six and one- 
half or seven jjounds per square foot of surface, 
to say nothing of the radical structural dissimi- 
larities in different successful machines. 

JCach prcncller is designed with three conditions 
in view : The most efflcieut running speed! of the 
engine, the speed through the air at which, with 
nroper pro])eller design the available power ought 
to carry the particular machine ; and the estimated 
head resistance at this speed. From this pre- 
liminary data is derived the winding or helical 
path to be traversed by every portion of the 
Itlade. and ever.v 6-in. section of the blade is de- 
signed with reference to the work it must do 
while traversing this path as an aeroplane (more 
properly "aerofoil") following a helical instead 
of a plane liorizon. Each different blade section is 
"iven a suitable form and angle of incidence to 
its horizon, according to its particular .speed, its 
necessary width and its relation to the other 
parts of the blade, and the entire number of sec- 
tions so determined are combined into a single 
blade having harmonious properties throughout. 
■I'bis method of design naturally results in a blade 
of variable pitch at different distances from the 
center. In the progress of every design this vari- 
able pitch and all the other important properties 
(if the blade, such as the gliding angles, co- 
etticienls of camlier, etc., for its different parts, 
ar(^ plotted in diagrams on special cross-section 
paper. 

In determining the blade area the principal 
consideration is that it shall be sufficient to 
keep the percentage of "slip" within the limits 
of good practice at all points, and the width is 
ai)portioned in a manner to give a fair distribution 
(if work over the principal portions of the blade. 
The varying gliding angles are arranged to take 
advantage of the inflow of air from the periphery 
and give it a sternward flow with the smallest 
amount of disturbance. The co-efflcients of camber 
niercentasic of curvature) for the principal por- 
tion (if the blado are derived from a consideration 
(if the width, gliding angle and velocity of each 
point — the elements of width and angle increasing 
the coefficient and the velocity reducing it. 

The diagrams of these varying features are of 
great interest, showing as they do, at a glance, 
all the different properties of the blade under 
its working conditions and making possible the 
ver.v ready comparison of different designs. 

Nearly all of the "Paragon" jtropellers have been 
designed in accordance with tlie principles already 
indicated with a view to their operation in actual 
lii'iht. rather than their caijacity to produce phe- 
Udmeual thrust, althonuh they seem to possess this 
capacity in greater degree than others. .V few 
designs, however, have been gotten up for heli- 
copter work, in which, of course, the standing 
thrust alone is the oliject sought. These designs 
|)roceed from a very different method of calcula- 
tion and are not adapted to keep un their 
thrust at any considerable axial speed. We are 
not able at this time to give full particulars con- 
c(>rning tests of these helicopter designs but we

THE MAKE-UP OF A BIRD'S W^ I N G 



By Dr. A. S. Rowe. 



H.WIX(; made n study of bird flight for years. 
I liavi> IxM'ii iiuicli interested in tlie article 
imhlished in your esteemed Aeuonautics. 
written hy I'rof. 11. La V. Twining, of Los 
Anyeles, entitled ; ''Can Man Fly With Win.!>s." 

These articles show a great deal of deep thought 
anid close investigation into the science of Ijird 
flight, l)ut have brought Prof. Twining to con- 
clusions tlie reverse from those proved out by my 
investigations and experiments, i. e., that the air 
does pass through the feathers of a bird's wings 
on the up or forward stroke, and if you will kindly 
allow me space in the columns of Aekoxautics. I 
will endeavor to give the experiments whicli led 
me to this conclusion ; not for argument's sake 
but for the beneflt it may be towards sol\ing the 
problems of the science of aerial flight. 

In the August number of Aeronai'tii's, I'rof. 
Twining, discussing the action of the up and down 
stroke of a bird's wings, says : "Much .si)eculation 
has been indulged in as to the feathers opening 
on the upstroke to let the air through, .lust a 
little intelligent observation of an extended wing 
will show how utterly fallacious this assumption 
is : Tlae feathers overlap so they shingle on top 
from th(> part near the body to the tip. On the 
underside they shingle the other way. In either 
case, as the air strikes the surface, the feathers 
bind together and present a solid surface to the 
air. The direction in which they shingle cannot 
make any difference in this respect. If we take 
up (he wing and blow violently on top of it, hold- 
ing the hand on the other side, no air will be felt 
coming through. If we blow against the under 
side the same result is obtained.'' 

Now, in order to arrive at an intelligent con- 
clusion regarding the stroke of a bird's wing, and 
the action, of air upon it during the strokes, we 
jnust understand the following points. 

First. — The mechanical construction of the feath- 
ers. Taking the feathers of a turkey buzzard or 
pigeon's wing we And the barbs of nearly equal 
length on either side of the shaft near the body 
of till' bird, and the barbs are of nearly the same 



flexibility on both sides of the shaft, those on 
the farther side being slightly the stifl'er : but from 
near the body the barb.s become longer on the 
inside of the shaft and shorter and stift'er on the 
opposite side of it with each successive feather, 
until in the feathers near the tip of the wing 
Ihe shaft is nearly to the outer edge — thus form- 
ing a long valve, so to speak, witii the shaft as 
an axis at one side. 

Second. — The position of the feathers in the 
wing. They are placed in the flrst third of the 
wing nearest the body of the bird, or out to the 
second .ioint, parallel with the body and al right 
angles to the front edge of the wing at their 
insertion, and their flat surfaces are nearly hori- 
zontal with the front edge of the wing; also wIk'u 
the wing is extended. From the second .ioint they 
diverge outward from a parallel line 'with the 
body until, in the buzzard's wing, when extended 
they attain a position nearly at right angle to 
the bird's l)ody. 

Third. — The relative position of one feather to 
.inother. The feathers lap or shingle nearlv one- 
half their width out the flrst third of the length 
of the wing. The barbs on that side of the shaft 
of the feather nearest the body under the pre- 
ceding one nearly their length. On. the other two- 
thirds of the length of the wing they lap under 
relatively less as the feathers diverge from each 
other. 

Fourth. — The relative proportions of the wing. 
Only about one-third of the length of a buzzard's 
or pigeon's wing is contained between the first 
two .joints; the other two-thirds being made up 
from this point out. The feathers are much 
longer and wider in this section of the wing 
and the width of wing is about on(>-third its 
length. 

Fifth. — The direction of the stroke of a bird's 
wing in relation to its body. The stroke varies 
according to the results to be obtained : as when 
in starting on flight the wing is raised much 
higher above the body and is brought farther 
below it, and the flexion of the wing is much less

than when the bird is in free flight, but on the 
up or forward, stroke it always moves upward 
and forward, and on the down strolve moves down- 
wards and backwards : thus making a rotary 
movement on the whole. The tip of the wing 
traverses a cycle corresponding to a curved line 
drawn from the tip of the bird's tail to the tip 
of the wing when extended. (See sketch.) The 
wing is not thrust forwards and backwards ex- 
tended, as though hinged at the bird's body, but 
is flexed at every joint including the one at the 
body, to a greater or less degree. Prom the sec- 
ond joint out is the area of greatest motion. The 
more rapid the flight the greater the flexion that 
takes place in the wing at each stroke. In every 
swift flight a pigeon closes its wing nearly against 
the body at each sti'oke. The action of the wing 
then is outward, upward and forward from the 




under each other as they do, are pressed against 
each other, which prevents the air from passing 
through upward : but on the up or forward stroke 
this pressure is temporally released owing to the 
rapidity of the upward movement — this movement 
being much quicker than the current of air pass- 
ing creates a slight pressure from above caus- 
ing the long flexible underlapping barbs of the 
feathers to spring slightly downward admitting of 
the free passage of air between them. Birds, such 
as the (juail, grouse, wild turkey and humming 
bird, which have a heavy body relative to the 
amount of sailing surface of their wings and who 
make their flight with a greater up and down 
stroke of the wings than do those having more 
sailing surface, will l>e found to have the feathers 
spread much farther apart in the outer two-thirds 
of the wings, the shafts of the feathers in this 
section being quite to the out edge, with the barbs 
underlapping much less, all of which is conducive 
to the free passage of air through the wing on 
the up stroke. And, too, another factor con- 
ducive to a free upward stroke of the wing, is 
the fact that the thrust is made in such a man- 
ner as to present the edges of the feathers, to 
a greater or less degree, toward the line of mo- 
tion of the wing. This is accomplished to a 
great extent by the forward edge of the wing' 
rising farther than the rear edge. There are, 
several reasons that prevent us from being able ' 
to see the light between the feathers of a bird's 
wings when they make the up stroke in flight 
when passing above us. Three of the main rea- 
sons are : That the stroke is made most too 
quick for the human eye to catch it ; the de- 
pression of the inner edge of the barbs of the 
feathers cause the feathers to assume more of a' 
curve, the lower edge of one feather cutting off 
the line of light coming through the next; a por- 
tion of the bird's body and tail would obstruct the 
line of vision through the wing, owing to the 
angle of the wing in relation to the bird's body, 
and that of the position of the feathers in the 
wing. 



body to the point of extension in the up or for- 
ward stroke, and the reverse in the downstroke. 
or downward, backward and inward towards the 
body. In the up stroke the front edge of the 
wing travels upward slightly farther than the 
rear edge, and the reverse on the down stroke. 
In normal straight-a-way flight the wing is ele- 
vated about as far above the horizontal line of 
flight in the forwai-d stroke as it is brought be- 
low it in the down stroke. 

Sixth. — The stroke of the wing relative to the 
line of flight. We see then that the forward 
stroke of the wing is made at an angle outwards 
from the line of flight something like forty-five 
degrees. The elevation and depression of the 
wing above and below the horizontal line of 
flight varies according to the lifting power re- 
quired, increasing with the greater light. 

Seventh. — The rapidity of the stroke of the 
wing in relation to the passing air. The bird's 
wing moving through the air on both the up and 
down stroke is always swifter than the motion 
of the air through which it is passing. Were 
this not the fact, a bird would be unable to rise 
from the ground ,and could not make headway 
against the wind. 

Now, from the foregoing, understanding the 
mechanical construction of the feathers, their 
position in the wing, their relative position to 
each other, the relative proportions of the wing, 
the direction of the stroke in relation to the body 
of the bird, the stroke of the wing relative to the 
line of flight, and the rapidity of the stroke in re- 
lation to the passing air, we are enabled to make 
a test of the point in question, and will ttke up 
the experiment where Prof. Twining left oft:', by 
taking the bird's wing and directing a blast of 
air downward against it in direct opposition to 
the up or forward stroke, as described above, at 
the same time moving the wing toward the air 
current, the same as does the bird in flight. 
The air will be found to pass through freely be- 
tween the feathers, and the air will pass in great- 
est volume through the outer two-thirds of the 
wing. On the down stroke, the feathers lapping 



Perhaps the failure of success of all the orni- 
thopters built up to the present time is due to 
the fact that they only partially emulate the 
different movements of a bird's wing when it is 
in flight, as by the foregoing we can see that it 
would be a very ditticult matter to make a ma- 
chine that would be capable of obtaining the neces- 
sary movements essential to extensive flight ; in 
fact, the complexity of such a machine would bar 
its usefulness. In Pig. 1, A is to represent an 
extended wing of a bird when in flight, B the 
flexed wing after the stroke, C the line traversed 
by the tip of the wing, if we were to look at it 
in the direction of the body during the stroke, 
should I he bird's body not advance but remain 
stationary. When the bird's body is advancing in 
flight the tip of the wing describes a series of 
loops. D represents the line of flight, and tne 
arrow the apjjroximate angle of the stroke of the 
wing in relation to thr line of flight. 

In the glider built by Dr. Kowe it has been 
attempted to follow the shape of the bird, with 
the turkey buzzard as the pattern. The machine 
is 30 ft. G ins. spread, planes 8 ft. fore and aft, and 
the total length 15 ft. The weight is but 44 
pounds. The depth of the curve of the jilanes is 
7 ins. at the central section of the niacliiue, this 
depth being at a point one-third back from front 
edge. This curve diminishes in depth until out 
10 ft. toward their tips the plant-s are flat. Prom 
this point they curve upward to their ends as well 
as curving slightly upward toward the edges, 
in imitation of a buzzard's wing. The dihedral 
angle is in exact proportion. The perpendicular 
rudders curve downward in a position to take the 
place of the sides of the liird's body and extend 
the length of the planes with the exception of a 
space near the center of eacli. which gives room 
for the operator's arms. The situation of these 
rudders is designed to prevent the machine be- 
ing turned around when going sideways to the 
wind. The bracing system makes the machine rigid 
at every point. After trials as a glider a power 
machine will be made of it.

THE first event of its kind and the largest 
aero meeting yet held in America was that 
organized by the Harvard Aeronautical So- 
ciety. Its official duration was from Sep- 
tember 3-13, though tlights were continued Sep- 
tember 14-10. 

The financial success of the aviation meet is 
not known officially. 

Unofficially it was claimed there had been deposited 
in the bank $126,000 receipts for the meet. The expen- 
ditures have been about as much. Paid admissions 
totaled 67,241 for 11 days. 

There was too much red tape in connection 
with the affair. Aviators found it more difficult 
to get to their machines than the public found 
it easy. Newspaper men were not treated verv 
well, it is claimed. To get in one a reporter 
liad to have a press badge good any place, one 
sood somewhere, one not good anywhere, a grand- 
stand ticket, a few ribbons and a health cer- 
tificate. 

(Jrahame-White did very well financially, outside 
of the prizes. He took up many passengers, and 
for each flight, it is unkindly rumored, his man- 
ager collected $50Cl — in advance. 

LAST TWO DATS. 

Boston, Sept. 16. — Claude Grahame-White, the 
English aviator, defeated Glenn H. Curtiss in a 
special race at Sfjuantum yesterday, thus bring- 
ing to a close the meet which has "been on since 
Sei)tember 3. 

The Englishman not only won over the American 
champion by a good margin, but he made better 
time for the distance of five and one-quarter 
miles than he did last Tuesday when he scurried 
around the course three times in 6 minutes and 

1 second. Yesterday he traveled an equal dis- 
tance, or three times around the 1% mile course, 
in 5 minutes 47 4-5 seconds, while Curtiss made 
the distance in 6 minutes 4 .■!-5 seconds. 

Grahame White's time for the first lap was 1 
minute 5B 2-5 seconds ; for two laps, 3 minutes 
3-5 seconds : for three laps. 5 minutes 47 4-5 sec- 
onds. The time of Curtiss for the first lap was 

2 minutes 4 1-5 seconds ; for two laps, 4 minutes 
4 4-5 seconds ; for three laps, 6 minutes 4 3-5 
seconds, o i ^;f-.-

In spite of many discouragements aiid' by perse- 
vering effort .James V. Martin, a special student 
at Harvard University and the director of the 
Harvard Aeronautical Society, succeeded in ob- 
taining the co-operation first of President Lowell 
of Harvard and then of Mayor Fitzgerald of Bos- 
ton, and subsequently several Boston business men. 
The idea took root and soon an exi)(nienced man- 
airer was found in the person of Adams D. Claf- 
lin. 

All the aviators except Grahame-White were 
housed in, two long canvas tents on opposite 
sides of the principal company street. The tents 
were 500 feet long by 50 feet wide and were ade- 
quate for their purpose. ^ 

(;»ue tent housed the following machines : Hub- 
bard monoplane, Curtiss biplane, C. B. Harmon's 
Farman biplane, two Wright biplanes, fire ap- 
paratus., Gaines' Clement-Bayard-Santos-Dumont- 
Demoiselle and the Harvard biplane. In the south 
hangar were the Bleriot monoplane and Farman 
l)iplane of Grahame-White adjacent to the two 
triplanes of A. V, Roe. Next came • the high 
liowered Burgess biplane operated by William Ilil- 
liard and two more Burgess binlanes. Models B 
and C entered by the Burgess Company and Cur- 
tis. Next were the Curtiss biplanes, one owned 
bv Augustus Post and the other operated by 
Charles F. Willard. Beyond these were housed 
the kites exhibited by Mr. Perkins. The Pfitzner 
monoplane and the Dixon dirigible were established 
in separate tents, provided by their owners. .\n 
A. V. Roe triplane has been purchased by tlie 
Hjirrai'd Afropautical Society.

THE I'lKLU. 

The clKiicc (il: gvoiinds fell iii>i}n Uic lua [■sliland 
;il. SyuauUmi. lyiug just across the Xeiiousot 
Uiver from the soutlieastera limits of the city 
of Boston. The grounds are in the form of an 
island : a narrow salt water creek separates it 
from, Ihi^ nminland and is bridged by a single 
I'oad. While most of the island is low-lying 
marsh, soft and soggy even in character, there 
are two strips of firmer ground, perhaps seven 
or eight feet above the level of high tides. One 
of these strips was assigned to the grandstand 
while on tlie other the hangars and sheds were 
located. 

The flying field lay to the west and north of 
the grandstand and included an area of irregular 
shape with a circumference of approximately two 
miles. The pylons were arranged for a circuit 
of one mile and three-quarters. While the field 
is probably the best availalile in the close vicinity 
of Boston and is adequate for the work of. pro- 
fessionals, it is not ideal for amateur aviators 
under existing conditions. The ■ space assigned 
for starting in front of the grandstand sloped 
slightly uphill and remained rough in spots in 
spite of the admirable work devoted to its im- 
provement. Then the layout of tin; course ro- 
((uired a turn to the left soon after starting in 
order to avoid the waters of Boston Harbor.' Un- 
fortunately just to the left and a few hiindred 
yards beyond the starting lin''. there was a deep 



gully in the marsh to trap the inexpert. It was 
this gully which l)rought the noted amateur, Clif- 
ford B. Harmon, to grief on the opening day and 
kept him from further participation till near the 
end of the meet. 

PROGltESS OF THE MEET. 

On Saturday, September a, the meet opened in 
threatening weather with a crowd of only mod- 
erate size in attendance. Grahame-White started 
on his victorious career by setting a good mark 
in the speed event as well as by establishing an 
excellent average in the bomb throwing, scoring 
:-'l points in 10 shots. The American profes- 
sionals, Curtiss, Wlllard, Brookins and Johnstone 
followed White into the air and gave exhibitions 
(if iilain flying without attempting any sensational 
maniieuvers. By winning the duration and dis- 
tance events on the first day .Johnstone laid the 
foundation for his final success in these two 
events. 

On :Monday the interest w.is increased by the 
first passenger carrying, (irahame-White and AVil- 
lard each taking up a lady passenger. 

On Monday and Tuesday. Mr. Grahame-White 
continued to increase his lead in spite of the 
rain and foggy weather, which prevailed, so that 
on Tuesday evening when the meet was one-third 
through he led the field with a total of 14.9 
points against a total of l.j 8-17 points for John- 
stone, Willard, Curtiss and Brookins combined. B^ 
Tuesday White led in every event except for dis 
tance, and in that he was only a single point 
behind Johnstone. Brookins did sensational stunts. 
The best records for the three first days were as 
follows : 

Speed — Grahame-White, (j minutes 1 seconds for 
514 miles. 

Duration — Johnstone, 1 hour 20 minutes 12 
seconds. 

Distance — Grahame-White. 4.") miles 617 feet. 

Get-away — Grahame-White, (56 feet 10 inches. 

Bomib-dropping — Grahame-White, 20 trials, 56 
points. 

The system of scoring points was a novel one 
and well arranged to develop constant coniixti- 
tion in all the events. Three points were awarded 
to the winner each day in each event, provided 
at least three entries were registered in that 
event. Two" points were given for second place 
.■ind one point for third place. In case less than 
Ihree entries were made on any day, the winner 
receivi'd two points and the second man one point. 
The events in which points were to be earned were 
speed, altitude, duration and distance. In addi- 
tion it was at first arranged to add the scoi'c 
made <'ach day in the liomli-throwing, but this was 
suhse(|uently changed so that only the average score 
per bomb thrown was added to the points won 
in the four events above mentioned. ICach liomb 
hitting the deck of a full sized outline of a bat- 
tleship from the height of KM) feet or more counted 
one point, while two funnels formed the Inills- 
eyes of the target, and a shot in them counted 
live. 

By Friday evening. Septenilier ;>. when six of 
the nine days had lieiMi completed, (irahanu'-^^'hite 
had still further increased his lead. Ills score by 
points had totaled :!o.2 against 17 for Johnstone, 
his nearest rival. Brookins had scored 10 points, 
while Curtiss and Willard were tied at 8. 

In the last half of the meet, however, the Wright 
operators started in consistimtly to earn points in 
altitude, duration and distance. Brookins I'arned 
5 first places in altitude in the last 5 days, while 
Johnstone accummlated 17 points in the duration 
and distance events. 

The final scores by points were as follows :

and was second in that event on four other days. 
Willard won flrst in speed once. 

The special feature of tlie meet was the $10,000 
prize offered by the Boston Globe for a two-lap 
flight around Boston Light and return. The course 
called for distance of approximately 33 miles, al- 
most all of which was over the water of Boston 
Harbor. Grahame-White made his first attempt 
in. his Bleriot monoplane on the fourth day of 
the meet and covered the course in 40 minutes 
1 3-5 seconds. This relatively slow time was in 
part duo to a detour caused by the aviator's lack of 
familiarity with the landmarks. On the next to 
the' last day of the meet. White made a second 
trial with th.o same monoplane and cut his time 
for the 33 miles down to 34 minutes. Making a 
fair allowance for the distance lost in the half 
dozen turns required, his average speed must have 
been over 00 miles an hour. 

The only hope of defeating Grahame-White for 
the Globe prize lay in (ilenn Curtiss' speedy flyer. 
The early days of the meet, however, had shown 
that the Bleriot with its 50' h. p. Gnome motor 
was faster than the Curtiss machine with its 50 
h. p. 8-cylinder Curtiss engine. Curtiss had 
to look for a more powerful motor. This 
he found in the new Indian motor rated at 
GO to 65 h. p. power which was owned by the 
Burgess Company & Curtis. An arrangement was 
quickly made to transfer this molor from the 
Burgess biplane flown ))y William Ililliard to the 
Curtiss flyer, and it was installi>d during the in- 
termission of Sunday, September ]1. T'nfortunatel.v 
there had been no time to tost out the new motor 
and when Curtiss attempted to fly with it, unex- 
pected carbureer troubles developed which were 
remedied only after two days of constant tinker- 
ing. The motor finally was put in running order 
on the last oflicial day of the meet, and he was 
enabled to overtake Grahame-White in his speedy 
Bleriot. But unfortunately the delay pi'oved fatal 
to Mr. Curtiss" chances for the Boston Globe prize, 
as the time limit expired before the motor was 
finally turned up. The Indian engine gave 430 
pounds thrust on a spring balance attached to 
the Burgess machine. 

Am'ong the amateurs the most notable event was 
the accident to Harmon's biplane shortly after 
making a start on the opening day of the meet. 
The accident was in ijart due to the soggy con- 
dition of the grounds after the continuous rains. 
Harmon was unal)lo to get up his usual speed 
before taking oft', so tliat his machine was travel- 
ing at a comparatively slow rate when it reached 
the first turn. The act of turning brought one 
wing tip in contact with the ground, and the 
whole biplane was precipitated into a gully across 
the course, which wrecked both supporting sur- 
faces, smashed the propeller and injured the motor 
itself. The running gear of the machine also was 
wrecked so that it seemed liopeless to attempt to 
replace it. However, W, Starling Burgess, a fel- 
low competitor, placed the facilities of his Marble- 
head factory at Harmon's disposal and returned 
the biplane to its owner in better condition than 
ever several days before the end of the meet. Har- 
mon, however, borrowed Mr. Grahame-White's Far- 
man biiilane and succeeded thereby in winning 
first prize for amateurs in speed, duration, l)(>iiih 
throwing and slow lap. 

Second prize among the amateurs was won by 
W. Starling Burgess in a Burgess biplane. The 
other amateur entries included W^illiam Hilliard 
in a Burgess biplane, who made two or three 
circuits of the course, but did not ofiicially com- 
pete because his powerful 60 h. p. motor had not 
been properly tuned up before it was loaned to 
Mr. Glenn Curtiss. .\. V. Roe, in his EnglishJ 
triplane, and H. F. Kearny in the I'fitzner mono-l 
plane, both met with disaster on landing afterl 
short flights. The only other amateur aviator," 
Augustus Post, made some short straight -away 
flights in his Curtiss biplane, but did not enter 
officially for any of the prizes. 

The meet was attended by many officers of the 
Army and Navy, as well as a large number of 
persons socially prominent. President Taft was a 
center of attraction one day and on other occa- 
sions Governor Draper of Massachusetts with his 
staff and the mayor of Boston added a political 
touch to the gathering. Thanks to Grahame- 
White, Mayor Fitzgerald went up in the air to a 



greater height than he had previously experienced. 
The success of the meet as a whole is a monu- 
ment to the initiative of James V. Martin, to 
the ability and perseverance of Manager Claflin 
and the aljle committees in charge. 



Perkins' Man -Carrying Kite. 

So far as known, the first time that a man 
has been taken up by kites for the purpose of ex- 
hibition in this country was at the Boston jneet, 
and this stunt is now the feature of tho kite 
exhibitions which Samuel F. Perkins nas been 
I)ooking at all the meets. 

A series of monster kites are used, from :) to 
IS ft. tall. Up to fifteen kites are employed, 
according to the velocity of the "Xvind and " the 
weight of the man. "It has beon. foLuid that a 
man can be lifted in a wind as low as IG miles an 
hour. An 18-ft. kite is first started and sent up 
for about a thousand feet, or until it reaches a 
steady current of air. Then a number of the j2-ft. 
kites are put on the liae, spaced about lOO ft. 
apart. These are added to as desired luitil the pull 
is found to be great enough to carry a man. 

At Boston Perkins himself went up about 125 
ft. on a Jittl? w:;oden seat slung by ropes, as 
shown in the picture. The rope used to liold the 
kites is one-half iucli in size and of the best grade 
that can be bouglit. The reel has to be very 
strong and well anchored. Miss Emily Willard, a 
sister of Aviator Willard, also went up in t'ae kite. 

Kites have been used to some extent ibrond for 
military measures. Not long ago experiments were 
made in England. It is alleged that the United 
States Army tried man-lifting kites some years 
ago, and Lieut. Wise actunlly went up a little way, 
but further investigations in this direction are 
said to have been given up. It will be remem- 
bered that the late Lieut. Thomas E. Selfridge, in 
1008, was carried up in a monster tetrahedral kite 
made by Dr. Alexander (iraham Bell, but on this 
occasion the kite was towed in the air above the 
waters of Bras d'Or Lake, by a power boat. 

I'erkins has been sort of a stand-by at all 
the exhibitions that have been held thus far, as 
his kites provided something for the crowds to 
watch at all times, if there was any wind at aJl, 
and as those who have had the more or less 
pleasant experience of visiting some of the flight 
exliibitions that have been held, know, a great 
deal of the time there is nothing but the kifeij to 
watch with the wind blowing too strong for the 
l)irdmen to do any "birding."

They were driven by an engine rated at 50 to 
60 h. p., but probably giving very much less dur- 
ing the test as it was running at only about 450 
to 500 r.p.m. 

In regard to details of construction, the usual 
number of laminations is five, but four are used 
in the smaller sizes and sometimes six for the 
largest ones. The plan form for each lamination 
is accurately designed and each pair for opposite 
blades of the same propeller are sawed out to- 
gether in duplicate to exact pattern and the holes 
for the dowels located by templates so that the 
registration of these lioles makes it impossible to 
put the several pieces together in any but their 
correct relation. The corresponding pieces in op- 
posing blades are selected from adjacent parts of 
the same edge-grained board, thus insuring the 
utmost similarity of weiglit, grain and texture 
in the corresponding portions of tlie blades. The 
accompanying illustration shows a group of half 
laminations for a 2-bladed propeller ready to be 
assembled and glued. 

.Vs for the best material, we have tried many 
varieties of wood but liave found nothing really 
superior to carefully selected edge-grain spruce, al- 
though we find nuartered white oak, hickorv and 
other hard woods very exct>llent, beautiful and 
durable for the smaller sizes in which a little 
more weight is desired or not objected to.

FLIGHT PROGRESS OVER THE COUNTRY 



c--^-^t?Kr: 




Curtiss Flies 129!/^ Miles Over Water. 

Oa August :!lst. (ilcnu li. Cmtiss Hew in his 
8-eylinder machine from iOuclid Urach. just east of 
Cleveland, to Cedar Point, near Sandusky. Ohio, air 
line distance of (>o..^ miles in 1 hour and 18 
minutes. The distance is about equal to that be- 
tween Poughkeepsie and the upper end of Man- 
hattan Island, which was one stage of Curtiss' 
trip from Albany to New York. The wind velocity 
was 12 miles per hour. 

The U. S. Ilydrographic Office at Cleveland 
figured the actual distance liaveled one way as 
64% miles. This gives a speed of 49.8 miles 
per hour on the outward trip. 

BEATS PIGEONS OX HOME THir. 

On September 1 the return was made but in 
much slower time, 1 hour and 41 minutes being 
consumed. The return was made, for part of the 
distance, in the rain, which stung the aviator's 
face. Some homing pigeons which were released 
at Cedar Point took 2 hours and .54 minutes to 
make the trip. 

Euclid Beach and Cedar Point are amusement 
resorts. The flight was made possilile by the 
Cleveland Press, which gave a prize of .$.5,000. 

Flying With Four Horsepower. 

We give some photos of aero|)lane experiments 
of M. B. Sellers in Kentucky. One of the pictures 



shows a rear view of the machine with a vertical 
rudder which can be made to assume a screw 
shape as described in article on Lateral Stability 
in May. 1910, Aeisoxautics. This was used long 
enough to prove the correctness of the principle. 
Note the keel, rudder and e(iuilibrium plane as 
originally designed and now used. The other pic- 
tures show ma'chine in flight. In these flights the 
Dutheil & Chalmers opposed engine was used. 
Six 1/4 in. auxiliary exhaust holes were bored in 
each cylinder, increasing the h. p. about 1.5 per 
cent. "The brake h. p. before boring holes wa.s 
about four. An Elbridge 2 cyl. 10 h. p. special 
motor has lieen ordered. 

Harmon's Flight Across L. I. Sound. 

Clifford B. Harmon made his long promised 
flight across Long Island Sound on August 20 He 
started from the aviation field at Mmeola about 
-.'iO o'clock. Thirty minutes later he lauded \n 
(Jreenwich. Conn., in a field next to the estate of 
his father-in-law. Commodore E. C. Benedict, an 
airline distance of 19V2 miles. . 

Mr. Harmon was unhurt. l)ut his Farman jra 
chine was damaged. The flight won for Mr. Har- 
mon the trophy offered by Coiniirii Life m Amriira 
for the first successful aemiilane flight across the 
Sound. Before starting on his trip across the 
Sound he made a flight with Charles K. Hamilton 
as passenger to test mil liis machine and to study 
the air conditions.

October, igio 



After making several laps he landed and an- 
nounced that he would start out to win the trophy. 
The wind was blowing about fifteen miles an hour, 
lu the flight to Koslyn. where he reached the 
water, the flying was over bad country. It was 
a struggle to keep right side up crossing Hemp- 
stead Bay, but he reached the I.ai'chmout Yaclit 
Club in safety and turned over the vessels in the 
harbor there at the international motor boat meet. 
From her(> he flew up th(^ Sound to the island just 
in front c)f his father-in-law's estate, landing on 
a sandy beach ,iust across an inlet, and came down 
in tall grass, after fouling some telephone wires. 
That accounts for the wrecked machine. 

Novice Flies 28 Miles Cross Country. 

William Evans, of S17.\ East l.'th street. Kansas 
City, Mo., was able to fly 2S miles across country 
on his second day's experiment with the .".O-foot 
Greene biplane fitted with an Elbridge four-cylin- 
der engine. The first day he received the ma- 
chine he made several fights back and forth the 
length of the half-mile field, with a propeller 
which was not designed to give a great deal of 
thrust. The next day he changed the propeller 
and made his 2S-mile flight across country. Glid- 
ing down, he could not iiick his landing and 
l)roke the front control. Percy Haslett, of Ala- 
meda, Cal.. and a man named .Tones, of Tomb- 
stone. Ariz., which latter ought to be a good 
place for aviators, have bought Elbridge engines, 
so there must be something doing. 

The Greene aeroplane which Roy Crosby, of 
San Francisco, bought has now been taken over by 
the California .\ero & Supply Co. 

, The Latest Wright Model. 

At tile .\sbnry I'ark meet the first public test 
was made of the new lou'^ distance Wright. The 
n\a(diiue is vei-y similar to the standard tyjie, witli 
th(> rear horizontal surface: practically the only 
change being in the fact that the horizontal rud- 
der in front is left off. In th(> places of this, the 
warpa))l(' horizontal tail serves to control the mo- 
tion up'and down. The advantare of this arrange- 
ment is that th(>re is nothing in the forepart of 
tlie macli^ne fo lie caught by sudden puffs of wind. 
.\s heret(>fore constructed, wind striking the front 
horizontal rudder acted with a powerful leverage 
on the ma«hine, due to the dislanci^ of ihe rudder 
in advance of the main planes. >i) such (>ft'ect is 
expericMiced with the horizontal riKider at the rear 
of the apparatus. 

The forward small vertical jilanes have been 
preserved in the new machine and are mounted 
in the framework of the skids. This rear hori- 
zontal surface^ is rigidly guyed to the outriggers 
for the forward third of its length fore and aft. 
I'^rom one-third back it is flexible and warped up 
or down, for steering up or down respectively, by 
crossed wires from the usual lever. 

The planes spread 89 ft. (the older machines 
were 41 ft. and the government flyer was 3(> ft.). 
The engine has greater borc^ than usual, being 
4% by 4. The weight is around SOO pounds. 

Wheels, flexibly mounted, are fitted to this ma 
chine, as we'll as to some of the other macliines. 

The machine is faster and can carry more wei';lii. 
It has not, however, the quickness of action that 
the others have, and is not ijuite so well ad.iptecl 
for cutting fancy figures, though to tlie layman 
there seems to be no diffi'rence. 

Constant Flying at Dayton. 

There is almost constant flying at the Dayton 
camp, which is proving of great interest to all 
who have the opportunity of seeing it. P. G. 
Parmelee is a new Wright aviator. The Wright 
comjiany has purchased a section of land in the 
west end of the city, and on the 7th instant broke 
ground for a group of buildings which are to form 
Ihe new factory. A double force of men are now 
(Ui the first building, containing 14,000: sq. ft. of 
fioor space which is to be used as the assembling 
room of iilanes and frames. The factory plan is 
of course of the most imiiroyed type, constructed of 
steel, brick and cement. 



Harmon Changes His Farman. 

Clifford B. Harmon's Farman machine, which 
was badly wrecked at Boston on the opening day 
of the meet, was repaired in record time and 
altered so as to make shipping and repairs less 
troublesome than heretofore. 

While the original dimensions and curvatures 
of the Farman biplane were retained, the wings 
were changed so that they are detachable from 
the central body in much the same manner as the 
Burgcss-Curtiss biplanes are arranged. The sur- 
faces can thus be packed in a space 12 ft. long, 
instead of requiring 35 ft. of space as before. 

The alteration was made by the Burgess Co. 
& Curtis. By rushing the force on September 
4th and .")th. it was possible to ship the new 
planes complete on September 8th, the time re- 
quired having I)een four working days. The job 
was undertaken on a Saturday night, and there 
was no opportunity to obtain materials or outside 
assistance owing to the apjiroaching Sunday and 
holiday. The men also had been given a vacation, 
with opportunities to attend the Harvard meet, as 
reward for several weeks of strenuous work. It 
thus became necessary to recall the force as far 
as jjossible by li'legraph anil engage Messrs. Wilson 
& Silsby. the Boston sailmakers, to work overtime 
preparing the cloth for the surfaces. 

Latest Curtiss Change. 

The Curtiss aeroplane used at the Boston-Harvard 
aviation meet by Glenn H. Curtiss presented a 
changed appearance from the machine formerly 
used by him. 

Althous^h the same engine w-as used as in his 
Hudson Flier the machine was altered to give 
it more sueed and cut down head resistance. 

The following changes were noticeable in the 
Curtiss machine : 

Camber of planes slightly less than in old style. 
Same surface as in Hudson-Fulton flyer. Ail- 
erons, four, forming rear of outer sections of upper 
and lower jilaues. working upward and downward 
and not down only as in Farman machine ; less 
liead resistance because behind planes; normal po- 
sition downward toward rear in line with rear of 
planes which brings them parallel to current of 
air iiassing over and under plane surfaces; front 
control is a single surface, with diamond-shaped 
\ crt'ical plane set stationary half above and half 
below. Same controls otherwise and same chassis. 
Outer sections of wings covered Ijoth sides. Middle 
sections covered oni' side. 

Woman to Fly Curtiss Machine. 

Miss P.lanche S<'ott. tlie yoimg lady who r(>- 
centl\- completed a I liins-contiuental trip in an 
a\itonioliile and was a passenger in a fliglit with 
C. I'\ Walsh in California, is exj>ect(>d to make lier 
debut at flying a CurMss machine during the exhi- 
hilinu flights in Chii-ago. preliminary to tin- start 
of the Chicago-New York race. 

New Design Biplane. 

-V. new type of biplanes is being experimented 
with by .Tames B. Slinn. of Chillicothe, 111., in 
which the forward control is done away with, 
using the upper i)laue for this purpose. Tli(» lower 
plane is of less spread than the upper and shorter 
fore and aft. The upper plane spreads 27 ft. by 
.'i-l. ft., and the under one 1 ."j ft. by .3 ft. .Vllow- 
ing for material cut away for propeller the sup- 
porting surface totals al)out 160. The rudder is 
3 ft. by 4 ft. Weight without pilot 340 pounds. 
The machine is mounted ou a 3-wheeled chassis. 
Materials, spruce and bamboo. .An engine of own 
make will drive a G ft. propeller placed in the 
rear. 

.\ man named Cooley is building in Uochesier a 
monster mononlane of 80-ft. spread. It resem 
hies nothing that has yet appeared in the aerial 
world. Two Elbridge engines drive two propel- 
lers. 



'I'he Cuiliss exhibition company now lias a Cur- 
tiss machine traxcling as a "dead exhibit" aro.iud 
the count IV to fairs and wherever there are no 
facilities for flight. Moving pictures are slunvn 
and a lecture given by Carl II. Carson.

Gentlemen : — 1 wish to express my admiration for the performance of the 40-60 " Featherweight " engine 
yesterday in the trial flight at the grounds of the Aero Club of Rochester. 

My machine was driven through he air at a rate of speed I had by no means anticipated. The effect ^n my 
feeling of speed and reserve power I can compare only to the exhilaration produced by a strong cocktail. 

I have used several different motors in my other machines, and to-day I am more than ever convinc d \.Vm the Elbridge 
"Featherweight" is the ONLY real flying machine engine on the American market. 

Cordially yours, 'Signed) W

FACTS ABOUT MOTORS I 




1 he Lall Aviation Lngine 



IS 



The 



1st. A Four Cycle Engine. Tlie type used on 99% of all automobiles and motoreyles. 
type used by all prominent aviators here and abroad, and Iiolding all aviation records. 

2nd. A Water Cooled Engine. The only kind that can be dependfd upon for extended runs 
without dangrer of overheating. Our spiral water jacket, together with piston pump circulation is 
the most perfect I'ooliufr system yet devised. 

3rd. An Opposed Cylinder Engine. The construction conceded by gas engine authorities to 
be the nearest vibrationless type. By all odds the construction best adapted for aviation purposes. 

4th. A Silent Engine. The only engine yet designed for aviation having both main and 
auxiliary ports silenced. Hence the only aviation engine adapted for permanent use, or for other 
than merely exhibition purposes. 

5th. A "Fool-Proof" Engine. The utmost simplicity of construction, small number of 
cylinders, together with its bjing of the usu;d Four Cycle type, enables any automobile chauff< ur to 
set and run it, not one in fifty of whom have any experience with Two Cycle, Revolving Cylinder, 
or V-shaped multiple cylinder engines. 

6th. A Thoroughly Dependable Engine. Our Magnalium outer casing for cylinders and 
cylinder heads permits of a remarkably strong construction with minimum weight ; while our Vana- 
dium Grey Iron Cylinder and cylinder head linings, piston heads, valve cages, valve seats, etc., is the 
only dependable material for these parts. 

7th. A Superbly Beautiful Engine. The entire design is thoroughly artistic : while all ex- 
posed parts not constructed of Magnalium— a shining non-con odible metal — are nickel plated, the 
whole surface being polished to a mirror finish. 

8th. A Phenomenally Powerful Engine. This result is secured by the use of a comparatively 
small number of cylinders of generous pro|)ortions, as distinguished from a multiplicity of cylinders 
with their numerous parts and bearings, and consequent friction, and liability to derangement. 

9th. An Exceptionally Economical Engine. It is a matter of common notoriety among gas 
engineers that economy of fuel, as compared with power developed, is .secured by large cylinders, 
few in number, rather tlian by ;i multiplicity of small cylinders— a consideration of paramount im- 
portance in aviation. 

10th. A Moderate Priced Engine. While the material and workmanship of this engineare even 
superior to the very expensive foreign makes, and not to be classed with the cheap engines Hooding 
the market, yet our aim has been to furnish avi itois with a moderate priced engine, cheaper than 
could be produced by themselves, except in large numbers, and with an expensive shop and foundry 
equipment. 

Other Aviation Engines possess a few of these advantages. This is the only engine that combines them all.

New Greene Aeroplane. 

A liiplanc built li.v Dr. William Creeno especially 
foi- cross country liyiug and long distance racing 
is now ready. It is of the same general style 
as other (ire(>ne machines, such as already de- 
scribed in detail in Aeroxattics. It lias a spread 
of 30 ft. with a chord of 7 Mi ft. and a curve 
depth of 2'/g in. A six-cylinder Elhridge engine 
is installed which actually gives on a I'rnnv brake 
test (UVo h. ],. 

Two sizes of (ireene machines are now being 
marlceted with prompt deliveries, 30 and :'>' ft. 
spread respectively. All the Greene machines are 
supplied with Elbridge engines and the Farman 
type landing arrangement, liO-in. wheels, 3-in. Pal- 
mer tires, r.osch magneto and Kl Arco radiators. 
On the large machines the wheels are 24 in. in 
diameter. What are called "practice skids" are 
being used in trial flights. These are fastened 
to the regular skids, as shown in the photograph. 
The large machine has a chord of ft. "i/^ in. and 
a depth of curve of 4^4 in. The ailerons, 1*)V2 ft. by 
20 in., are attached to the rear struts instead of 
being between the surfaces as in the Curtiss ma- 
chines. These ailerons are operated by the usual 
shoulder control. 

Instead of using sockets as formerly, aluminum 
castings are now employed for connections. The 
surfaces are of Irish linen with a special prepara- 
tion whicli is- put on after the surfaces are in 
place. The cloth is stretched as tight as a drum 
head and has a breaking strain of 71 lbs. per 
scpiare inch. The front control is a little smaller 
than that employed in the former machine (of 
which full drawings were pulilished in Akuoxau- 
Tics. I. Also, there is a flap attached to the rear 
of the back horizontal surface which works in 
conjunction with the elevator through crossed 
wires. The whole rear horizontal tail can be 
quickly shifted to various angles of incidence, 
merely by loosening a metal clamp around the 
short vertical posts at the extreme end of the 
outriggers and ri'damping at the desired place on 
the post. 



Baldwin Flights at St. Louis. 

St. Louis, Mo. — ('apt. T. S. Baldwin made some 
tine tiights along the river front on September 
10-12. The.se tiights were his first real ones at 
an exhibition and no one can kick at the "young 
man" now. In one of these, taking 10 minutes, 
when he crossed over three and flew under two 
bridges while in the air. Including the time he 
was on the ground between the flights, it was 
rhirty-six minutes from the time he started until 
he landed on the aviation ground again.

AT THE MINEOLA AVIATION GROUNDS 



Review of the Month's Flying. 

The past month at Minoola has not seen quite 
so much flying as heretofore since Harmon's flight 
across the Long Island Sound, as the machine 
was damaged ou that occasion and later was 
shipped to Boston. Capt. Baldwin has been away 
and II. S. Harkness with liis Antoinette has been 
doing nothing more than running over the grass, 
getting used to the grounds and machine, after 
i)eiug out of the game for some month,s. Joe 
Seymour has been flying constantly right along. 

Tod ("Slim") Shriver has brought out a new 
machine of a general Curtiss type, in which the 
ailerons are outside of the main cell and attached 
to the rear supports. Equipped with a Kirkham 
six-cylinder engine, he has been making some good 
short flights. The machine was constructed l)y 
Mr. Shriver for Howard Dietz. 

The second week in September, P. Brauner & 
Co. brought out one of their stock machines of a 
general Curtiss type, 30 x 41/0 ft., fitted with a 
British-American 2G-h. p. stock automobile engine 
driving a Brauner ft. diameter 4^/^ ft. pitch pro- 
peller, giving at 900 revolutions 1S.5 lbs. thrust. 
Some short flights have been made in it by D. Mas- 
son, who was mechanic for Paulhan when he came 
to America. The front elevator is a single surface. 
Equipment includes the El Arco radiator, Bosch 
magneto and Palmer tires. 

Frank Van Anden has another biplane ready 
for trial, fitted with a Cameron air-cooled auto- 
mobile engine with auxiliary exhausts. It would 
be of interest to know how this cools and to see 
with what success flights are made, as the engine 
is rated at but 24 h. p. The running gear is sim- 
ilar to Capt. Baldwin's, with the front wheel off 
the ground. Pennsylvania 20-in. wheels and 4-in. 
tires are used. The motor has a Splitdorf mag- 
neto and Breeze carburetor, as generally supplied 
with Cameron engines. 

Dr. II. W. Walden is building a shed of his own 
and is progressing with the remodeling of his 
wrecked monoplane. The new one will have Penn- 
sylvania 4-in. tires and the holes in the ground 
won't be so effective. 

An innovation in cooling systems is employed 
by George Russell and J. J. Frisbie. Two small 
El Arco radiators are used, placed one on either 
side of the operator, where they get all the air 
there is coming. These work very satisfactorily 
this way, and the head resistance does not seem to 
have been any objection. 

G. E. DeLong, designer of the Elbridge engine, 
has started a training school, using a Shneider- 
built Curtiss-type aeroplane, which he purchased 
some time ago. E. P.. Gaskell, 2308 Seventh ave- 
nue, New York, and F. E. de Murias, Babylon, 
L. I., are the first pupils. Wisely enough, the 
school does* not undertake to pay the damages 
sustained in trials. 

W. L. Fairchild is out mornings and evenings 
practicing with his big monoplane, fitted with an 
Emerson six-cylinder engine, about which he is 
enthusiastic. It drives by a chain two propellers. 
The George Russell machine has had its power 
plant changed over from a Curtiss to a four- 
cylinder Elbridge. The first part of September 
he gave exhibitions on Staten Island. One of the 
most successful experiences he had. was a collision 
with a cow. So far as we are able to ascertain, 
this is the first time that an aerial milking has 
been attempted. 

Sam Barton, of 238 Dumont avenue, Brooklyn, 
is putting together in the Aeronautical Society's 
sheds a small Ijiplane with a two-cylinder Elbridge 
engine. This more or less resembles a Curtiss 
machine. The elevator and the horizontal tail will 
work in conjunction. The machine is only par- 
tially assembled thus far. Hartford tires are be- 
ing used on specially built home made wheels. 

Miss E. L. Todd has a Rinek eight-cylinder 
engine. 



Nicholas Rippenbein is completing the assem- 
bling of a light Farman type machine which was 
bought from Fred Shneider. The ailerons in this 
machine are between the surfaces, and instead of 
being hinged at the struts and moved up and down, 
are mounted on la shaft running fore and aft be- 
tween the main surfaces. At the end of the shaft 
is a grooved pulley over which crossed wires run. 

Harry Chandler, of the Auto & Aeronautic Sup- 
ply Co., and Glenn Ethridge, both of Westbury, 
L. I., are building a biplane of radical construc- 
tion as regards sockets, engine beds, controls and 
angle. This is now ready for trial. The equip- 
ment includes an Elbridge four-cylinder engine, 
A-Z radiator and tank, and Hartford tires. 

Philip W. Wilcox, of the Columbia University 
Aero Club, has had bad luck. His first trial some 
two months ago, resulted in smashing the running 
gear on the ground. Charles K. Hamilton flew 
it next time and broke up the landing arrangement 
again. After it was all fixed up anew, stronger, 
and with big 4-in. Pennsylvania tires, Wilcox at- 
tempted flight himself and succeeded at the first 
jump, with all the power of the Rinek eight- 
cylinder engine behind him. For some little time 
flights were made before the machine was" reduced 
to a wreck. He is now going at it again and will 
build two machines. With a Rinek propeller, 7%- 
ft. diameter by 4-ft. pitch, the engine gave over 
350 lbs. thrust standing. 

The Garden City Co., which erected a fence 
and grandstand around the grounds and now 
charge admission whenever there is a sufficient 
crowd of sightseers, has established a system by 
which the aviators receive a certain portion of the 
profits, proportioned according to the extent of the 
flights made by each. 

The erection of the fence, the independent atti- 
tude assumed by the Company and the alleged non- 
fulfillment of promises made by it has resulted 
in considerable friction. The Aeronautical Society 
has given the Aero Club of America an oppor- 
tunity to join in a protest and issued a statement 
of which the following is a part : 



August 22d, 1910. 

The Garden City Company, 

60 Wall Street, New York City, N. Y. 

Gentlemen : — When you recently (with- 
out our consent) erected a high fence 
around the property which you leased to 
this society at Mineola and constructed 
a grandstand and ticket office, you argued 
it advantageous to us and promised to ac- 
count for all funds and see that condi- 
tions were improved generally. You now 
refuse to account for what you have col- 
lected and spent and are continuing to 
force the public to pay money to you to 
witness the flights of members of this and 
other clubs on your ])roperty. You are 
also collecting money for other privileges, 
such as stands, sign spaces, etc., and the 
public are led to believe that we are the 
interested parties, although we never have 
been and do not wish to be interested in 
the receipts of your enterprise. 

We object to this method of exploiting 
our memljers. Had you turned these mat- 
ters over to a joint committee represent- 
ing all interests, the members and their 
friends would not be repeatedly inter- 
fered with by the representatives of your 
real estate, and everyone legitimately in- 
terested in aeronautics would have been 
better satisfied. 

In view of the foregoing we are obliged 
to notify you tliat if conditions are not 
improved we shall be obliged to restrain 
you from further interference with our 
rights on the property. 

The Aeronautical Society.

t'. S. I'eets aud Ii. C Tcetor. of the Hudsou-

Xi'w York, will shortl.v bi'^iu trials at-Mineola with 
a biplane, principally on the lines of a Curtiss. 
with Farmau t.vpe runuiny- gears. Messrs. P<'(>ts 
nnrt Teotor were members of the West 8iclo Y. 
M. C. A., aero class of li)09, with Will)nr R. 
Kimball as instructor. 

Will)ur R. Kimball is al)Out to begin the con- 
struction of an entirely new type of machine, 
after a year of laboratory worl\ and experimenting 
with the object of combining lifting power and 
th(> propelling force of i)ropellers in connection 
with i)lanes. .V model has been constructed and 
successfully tlowu that shows remarkable proper- 
ties of equilibrium and ease of control, and an 
increase in the thi'ust obtained from propellers. 

Frisbie New Mineola Star. 

.T. .T. Prisl)ie has been the sensation of the 
Mineola rteld. lie did not spend any time running 
around the ground, but attempted flight the lirst 
crack out of the box. and has been flying regu- 
larly every day. with the exception of the tirst 
half of September, when he arrived at Rochesiei'. 
He has proven to be one of the most apt students 
of flight that has been seen at Mineola. 

TRI.\LS AND TRIBULATIOX.S. 

Krisliie first appeared in the aviation camp at 
.Mineola early in the s]iring. lie had a few luui- 



dred dollars and the determination to become an 
aviator. Someone offered to sell Frisbie an aero- 
plane, all right from the ground, splendid motor, 
etc. And Ifrisbie spent weeks that ran into months 
waiting for the demonstrating flight, — which 
never came. After a long time a machine was 
alleged to be assembled and a thing called an 
aeronautic motor was installed. The outfit col- 
lapsed after a run estimated at eighteen seconds. 
Frisbie had spent thirteen weeks and all his 
money waiting for it. 

He returned to Rochester with five cents in his 
pocket, a number of obligations, among them the 
support of a family. About the only thing he 
had left was determination to win out, and a lot 
of friends. 

After further weeks of trial he secured enough 
l)acking to insure the building of his own "plane, 
and he ordered an Elbridge engine. In less than 
a month he was ready for the air. and twenty-four 
hours later he had made five short flights. 

If the affair had been less serious. Frisbie's 
tirst flights would have been humorous. Advised 
not to leave the ground for at least a week, Frisbie 
started virtuously to run across the field to learn 
the use of the different controls, but he reckoned 
without the thrust of the 40-h. p. two-cycle engine. 
It never occured to him to throttle down, so in 
a few seconds he was bounding across the field at 
a terrific rate of speed : a piece of rough ground 
jarred bis arirjs enough to affect the front control,

and less than half a minute from the time of 
all his good resolutions he was in the air, 20 or 80 
feet above the ground. He wavered, he wobbled. 
the machine slanted from the torque of the pro- 
peller; Frisbie had presence of mind to straighten 
np and to try to get nearer the ground. No diffi- 
culty about that ; he pushed the control forward 
half an inch and the machine dove for the ground 
like a falling skyrocket. Frisbie yanked back on 
the control to avoid the ground, and started up 
on an angle that suggested an attempt to loop the 
loop. 

He landed unharmed, however, and started out 
again. Day after day he kept at it, practicing 
whenever the breezes dropped below 10 miles an 
hour. In two weeks ho had successfully accom- 
l)lished a 10-mlle cross country flight, flying two or 
three times around the fleld as a preliminary, 
and then, without descending, starting out across 
country and flying over the polo fleld at the 
Meadow Brook Club, circled over the Motor Park- 
way, passed over Westbury, and returned to the 
fleld in 14 minutes from the time he started. 

On another occasion, when Acting Mayor Mit- 
chell of New York visited the fleld, Frisbie made 
several flights in the rain. He also has made a 
flight of some miles after dark, and safely carried 
his son as a passenger on one of his early trips. 

At Ontario Beach Park, near Rochester, N. Y., 
on Labor Day, J. J. Frisbie made his first appear- 
ance as a professional aviator, just about three 
weeks since he made his first tentative flight at 
Mineola. There Mr. Frisbie, anxious to make good 
before his backers and fellow-townsmen, tried one 
of the most difficult things so far attempted by any 
aviator. The only place from which he could 
get any start was a bit of lawn about 200 feet 
wide, bounded by poles, a hotel, a merry-go-round, 
and sideshows; in front steep rollers piled them- 
selves on the beach, driven l)y a high wind. Not 
counting the people who crowded around the ma- 
chine, the actual space between material obstruc- 



tions through which Frisbie had to guide his 
■plane was exactly 40 feet. Minor embarrassments 
were two asphalt sidewalks he had to cross, each 
high enough above the level to smash the wheels 
on his flrst attempt to rise. Four times he started. 
and four times dropped into the lake, but the fifth 
time his nerve and perseverance triumphed and 
he rose safel.v to a height of 50 feet and sailed 
around the park, only to be again obliged to 
land in the surf because the dense crowd left nol 
a foot of space on the shore. 

After being fished out of the water the first 
time, the gasolene valve was found to be closed. 
The gasolene was turned on, and off the motor 
started. The Atwater-Kent coil was changed the 
next day for a magneto. One trial resulted in a 
smash on the sand, and he had to fly the next 
time with a split propeller patched up with tin 
on one blad". Vnother time the mo(or short- 
circuited itself just as he was out over the lake. 
The next time the iiropeller was smashed when it 
struck the water, lo prove that he can fiy, Fris- 
l)i(> decided to stay in Rochester until he could 
eitlu'r fly across the city or cross Lake Ontario.

Flies With 5 H. P. 

DONALD ir. GORDON, of Bostonia, Cal.. lias 
a biplane with which he has been, doing 
some remarliable worlv. The macliine has 
a 5 li. p. cyl. motorcycle engine, and with Uii5 
motor and a geared down propeller of his own 
manufactnre. he claims to have made flights of 
up to 500 ft. in length. As the weight of the 
machine complete with oi^erator is 380 pounds this 
would give a load carried per h. p. of 76 pounds, 
which is remarkable. The machine in general con- 
struction and detail remiuds one of the Roe tri- 
plane, inasmuch as the same low li. p. is used, and 
it has the same inverted triangular fusilage and 
general appearance. Following is a description : Top 
plane 20 ft., lower i.'4 ft., chord 4 ft. Distance 
between planes 4 ft. 4 ins. Angle of incident 
same on ground as in flight, abovit 7°. Planes 
are constructed with a view to automatic 
balance, and so far Mr. Gordon has never had 
an occasion to use the lateral stability device 
which he has also placed on the machine, even 
when flying across a 15-mile wind. He claims the 
machine would tilt to .'50° angle when struck by 
gust, but would right itself automatically. Cam- 
ber of chord. 2% ins. in 4S ins. Planes in three 
block sections, semi-circular rudder operated by 
foot lever, double front elevator, 32 sq. ft. area.

coils. Proi)eller, ft. diameter, 5 ft. 8 ins. pitc-h. 
cedar and spruce of ^Ir. (iordon's own manufacture. 
The motor is speeded to 2.100 revolutions and 
drives a geared down propeller at a little over 
seven hundred. Weight of machine complete 240 
pounds. Mr. (iordon's weight is 140 pounds. A three- 
wheeled chassis is used with a novel type of 



suspension of the two rear wheels. The two-leaf 
spruce strips with axle attached in center are 
pivoted at the front and are attached to skid at 
the rear by springs. Mr. Gordon's longest flights 
have so far been from 450 to 500 ft., which is the 
longest distance engine will run at full speed with- 
out overheating, which of course causes it to slow 
down. He is now putting in a cooling fan and ex- 
haust ports to keep the motor cool for longer 
flights. He is also installing a 7 ft. propeller to 
run at a slower speed than the present one. The 
fields are so rough around his vicinity that he 
claims that it is very hard to build a machine 
capable of standing the racking. lie has had very 
little trouble, however, beyond breaking a wheel 
or two. Mr. Gordon has also had considerable 
experience with gliders, having made in the neigh- 
liorlmod of 50 flights of about 150 yards in leng-th. 
In all of these, he says, he never had the sug- 
gestion of an accident and hardly broke a stick, 
reached heights of 20 ft. and flew in winds about 
15 miles per hour. lie uses an inclined rail with 
his glider. 

.1. E. Clark, of San Francisco, has a biplane of 
the new Farman type near San Jose, Cal.. in which 
he is said to have made some very good flights, 
the longest of about a mile. The machine is 33 ft. 
spread on the top plane and 21 ft. on the bottom, 
by (> ft. 3 in. chord. 30 ft. fore and aft, single 
laminated ribs. A Sommer type chassis is now 
used but will be changed to the four wheel Farman 
type. .\n Klbridge 40-60 h. p. engine drives direct

has not been measured. Bosch magneto is in- 
stalled. Lateral control is by shoulder brace con- 
nected with semi-circular ailerons l)etween the ends

similar to the Curtiss with the usual wheel. Curva-

Charles Bradley, of the Paciflc Aero Club, an 
account of whoso large, high pitch, propellor test 
was in the September issue of Aeron.\uticSj, got 
off the ground, for a short jump, with his biplane 
on September 5 in the presence of your repre- 
sentative. The clutch would not hold, however, 
machine came down and ran into a ditch, the axle 
bent in a semi-circle but the "Camsc" wheels did 
not "dish." 

Mr. Bradley said that all he wanted to know 
was if he could get off the ground with his large 
propeller and small horsepower, and as he was 
successful in this, and the machine was of rather 
crude construction he demolished it and will now 
begin work on a new one. 



By Prof. H. La V. Twining 

In January, 1910, after the Los Angeles mid- 
winter meet, Chas. K. Hamilton went to San 
Diego, Cal., and spent three days flying on Coro- 
n,ado Island. On this occasion he flew across the 
bay and down the beach into Mexico and return. 
At this time Chas. F. Walsh, of San Diego, had 
a monoplane which he attempted to fly. Instead 
of flying, the machine ran into a fence and be- 
came a total wreck. By May 2, lOlOi, Mr. Walsh 
had constructed a biplane of the Curtiss type with 
which he is flying. Since that time he has made 
some 20,0 flights of 500 feet to 114 miles in 
length, reaching an altitude of from 10 to 80 feet. 
Mr. Walsh has modifled the Curtiss method of 
control, using a design of his own devising. The 
machine is etjuipped with a 40 h. p. Elbridge en- 
gine. The aeroplane weighs 380 pounds and has 
400 sq. ft. of surface. It spreads 40 feet from 
tip to tip. 

Mr. George Duessler has been making short 
flights in his biplane at the Los Angeles aerodrome 
where the Aero Club of California has its head- 
quarters. The flights average some 300 feet. On 
one occasion he covered 495 feet, just missing the 
winning of the Knabenshue cup. 

The wiruier of the cup must fly 500' feet under 
power in a machine of his own construction. He 
must also be a member of the Aero Club of Cali- 
fornia. The last of August Mr. Duessler blew 
out a cylinder head and is now repairing his 
engine. J. J. Slavin is also having trouble, 
but will soon be in shape to again try 
for the Knabenshue cup, after his accident of 
a few weeks ago. On this occasion he rose from 
the ground at too sharp an angle, to an altitude of 
25 ft., where the machine lost headway, resulting 
in a crash to the ground. Several members were 
broken and the running gear was smashed. Mr. 
Slavin escaped unhurt. Slavin has a 3 cyl. 30 
h. p. Elbridge engine. 

On August 28 the Cannon brothers towed their 
Curtiss biplane behind an automobile. The ma- 
chine rose some 10 ft. above the ground where 
it was maintained by use of its controls. This 
furnishes excellent practice, and as soon as they 
get their engine installed we can expect some 
flying. On several of their towed flights they car- 
ried a passenger. 

The Twining ornithopter, number 3, was given 
a trial last week. This model weighs 115 pounds 
and the operator 150 pounds, making a total weigh 
of 265 pounds. The wings are 12 ft. long by 
ft. wide, giving about 100 sq. ft. of surface. Moij 
powerful leverages were used in this model and 
good up stroke of the wing developed. 

The experiment developed a slight drive along 
the ground, and on one occasion it rose bodily from 
the ground to the height of one inch, upon the 
down stroke of the wings. Early in the trial one 
wing was l)roken so that it became flexible around 
its front edge. In this condition the wing drove 
the machine forward but lost in lift. 

This model is a great improvement over model 
No. 2, a lift of 205 pounds being obtained as 
against 120 pounds in the otliin- one. Larger 
and stronger wings will be constructed and an- 
other trial be made this fall. 



Hamilton Injured. 

Chas. K. Hamilton, flying for his own account 
a brand new machine on the style of a Curtiss, 
but fitted with a 100 h. p. engine built to order 
by Walter Christie, met with an accident while 
flying at Sacramento, Cal., on September 9. In a 
previous flight the machine was damaged, but the 
aviator unhurt. He was burned by the water 
from the radiator and severely cut and bruised. 
It is believed there will be no serious results.

MEETINGS COMING, GOING AND GONE 




IRT SHEEPJHEJiDBAr 



Asbury Park Meet Concluded. 

The flying by lii-ookius, lloxic, Coffyn and John 
stone proved so satisfactory to tlie Astniry l'arl< 
committee tliat tlie series of fliglits were continued 
up to and including August liTtli. Tlie m»^i't be- 
gan on August inth. 

To cover fully the various stunts performed by 
the Wright machines under the guidance of such 
skillful aviators would take <a number of pages of 
the magazine. From :', o'clock in the aftemoou 
till almost dark there was something doing ever.-*' 
day. Flights were made out to the ocean and 
back, to various nearby resorts ; on one occasion 
a landing being made on the Deal Beach Golt 
Links, the machine was started again and the 
return made. This flight was by Brookins and 
Coft'yn, a passenger flight. 

NEW WORLD'.S llECJOUD. 

Walter Brookins. whose nose was seriously dam- 
aged when his machine was wrecked against the 
grandstand on the niiening day. was nut out of 
commission long. On .Vuu'ust L'.'id be shattered 
bis former record for a eiiMiplcft<' eirele by making 
one in ."ii/^ seconds. .lobnstone n ide numerous 
high flights, going up to .'{.(lOii feet: and many of 
the flights lasted ."0 to 45 minutes. 

4.0(»0 FKET nirjii. 

On the I'.Mb Ilii.xie and .Tohnslene eacli made 
moonlight flights with none for spectators save 
the birds, and they were asleep. In the afternoon 
of the same day Iloxie was np for ."iL> minutes, 
reaching an altitude of 4,000 feet. 



AERONAUTICS EDITOR RIDES. 

On two occasions novices were taken up for 
rides, only •'joy rides." as the aviators call flights 
of ten minutes or so. The publisher of Aero- 
N.viTics. K. r.. .Tones, was one of these two lucky 
individuals, and the star reporter on the New 
York Sim the other. Brookins took the former 
on the latest machine, minus the front control and 
mounted on wheels, up to 500 feet, sailed around 
the field a number of times, made two of those 
short circles for which Brookins is so famous, then' 
shut the motor off and slid rapidly to the ground. 

It actually makes one's heart alnwst stop beat- 
ing to see Brookins start his aeroplane downwards, 
tilt up on one corner and then make a hole in the 
air like a cork-screw in a cork ; but to Ik- a pas- 
senger on one of these whirls, find yourself slip- 
ping sideways off the seat, with the green grass 
showing in a nice little siiuare patch down be- 
low through the en<l of the phnie. is some ex- 
perience. The i)assenger is likely to wonder if it 
is not possible that on this one occasion a puff 
of wind may carry the machine just a degree or 
two l)eyond !>o, with a finale in, l>avy .Tones' locker. 

This is real flying and a passenger's sensation 
in a flight like tliis varies considerably from those 
in a straight -away a few feet off the ground. After 
such an expi'rience the passengt'r is likely to have 
considerably more r(\spect for the capabilities of 
I be exiiert l)ird-men. Yet one must consider that 
this was but a commonplace "joy ride," for the 
intrepid Bi'ookins is doing these stunts day after 
day, in his efforts to "demonstrate." as he says, 
"the practicability and safety of the Wright aero- 
plane."

Sheepshead Bay Meet. 

BY FilAXK S. TILLMAN. 

New Yorkers were given their first real aviation 
meet tlie last two weeks in August, at tlie old 
Sheepshead Bay race track by Glenn H. Curtiss. 
and his flock of birdmen. composed of J. C. 
("Bud") Mars, Chas. F. Willard, Eugene B. Ely. 
J. A. D. McCurdy and Augustus Post. 

Several experiments that proved the Heropla f's 
value in a new sphere were successfully accom- 
jpffshed during the six days the birdmen were 
flying at the field. 

The greatest of these was the wireless telegraph 
message sent from an aeroplane in flight by .1. .\. 
D. McCurdy to II. M. Horton, the designer and 
operator of a practical wireless outfit especially 
adapted for sending messages from an aeroplane 
in flight to a ground station. 

Next in importance, from a scientific standpoint, 
was i^he test for marksmanship with a regulation 
U. S. Army Springfield rifle, b.v Lieut .Jacob 
Earl Fickle, 29th Infantry, who fired and hit a 
target placed on the ground while aloft a hundred 
feet with Glenn H. Curtiss. 

The meet opened on Friday, August 19, tand was 
originally intended to last but Saturday, August 20. 
and Sunday. August 21. Due to the success of the 
first three "days the meet was extended and lasited 
three additional days of Friday, August 26th and 
27th, closing on Sunday, August 28th. 

The opening day was featured by the number 
of passengers carried by Curtiss and Mars. A 
representative of every New York daily newspaper 
was given a ride either by Curtiss in his Hudson 
Flyer or by Mars. 

It was on one of three trips when he had 
Frank D. Caruthers, a well-known New York news- 
paper man, as passenger, that aviator and pas- 
senger all but came to a disastrous finish. Mr. 
Caruthers has the distinction of being the heaviest 
man ever carried as a passenger in a Curtiss 
aeroplane, his weight being over 195 pounds. It 
was this fact, however, that nearly resulted in 
an accident. 

As in all his passenger flights Mars started ai 
the upper end of the field and after a short riu 
flew gracefully to the lower end. Instead of sto/) 
ping there with Mr. Caruthers. Mars deterniin/'d 



to make a turn and land his passenger at the 
starting point. 

Half way around an extra stiff puff of wind 
caught the heavily-weighted aeroplane and in an 
instant the machine was thrown almost on its 
side. For fully a minute there followed a pretty 
bit of air jo keying. It required all of the skill 
of Mars to regain control of his pitching, tossing, 
tumbling machine. Experienced aviators on the 
ground held their breath at the sight and when 
Mars finally succeeded in weathering the storm and 
brought his machine safely to the ground he was 
greeted with a round of applause. 

The flight, which was Mr. Caruthers' first trip 
in an aeroplane, had not impressed the passen- 
ger as it did Mars. Caruthers, when he finally 
climbed out of his seat to the ground, confessed 
that he had failed to realize the danger he was 
in while Mars was having his struggle in the 
air. The real danger to Mr. Caruthers appeared to 
be at the moment of landing when the aeroplane 
hounded over the ground. 

In addition Mars took his wife, Mrs. Ely, wife 
of .Wiator Ely : .Joseph Pulitzer, .Jr., of the New 
York Worhl, and Capt. H. Kerrick of the U. S. 
Army, and others, for a short .I'oy ride through 
space. Willard also took up passengers. 

On Friday, the 19th, four machines were in 
the air over the same field, and all flying in the 
same direction. 

On August 20. Lieut. Fickle, in service uniform 
with a full round of Ijall ammunition, first made 
<i trial flight with Mr. Curtiss to determine if 
the viliration of the aeroplane would destroy his 
aim with a rifle. Finding that it would not, he 
placed a target in the center of the field of about 
three by five feet in size. 

Then as a passenger with Mr. Curtiss he soared 
about 100 feet and fired downward while directly 
oyer his target and struck near the edge of the 
mark. 

/ Notable was the sending of a wireless telegram 
/by McCurdy on August 27th, from his aeroplane 
• while high over Sheepshead Bay, to II. M. Horton 
on top of the grandstand at the track. The 
message was received by Horton on the top of the 
grandstand and handed to the group of newspaper 
reporters. 

In order to develop the aeroplane wii'eless Mr. 
McCurdy and Mr. Horton since the meet have been

October, igio 



at the Curtiss factory, at Hammondsport. N. Y., 
whiTo thoj' have been making daily trials with tho 
wireless apiiaratiis. which has resultpd in unusual 
results, messages liaviuji been sent as far as five 
miles to tlie stationary set from the aeroplane 
in flight. 

When the final tests had been made and Mr. 
McCurdy was ready to make a flight and try out 
the instruments he was given what was destined 
to be the first wireless message ever sent from an 
aeroplane. It had been written by Mr. Caruthers 
at the request of ^Ir. Curtiss a week before. Mr. 
Caruthers has carefully preserved the original of 
the message wliich he prizes as one of his most 
valuable possessions. 

The flights on August 26th were featured by 
the narrow escape and sensational flight made 
by Augustus I'ost. the amateur aviator, in a 
Curtiss biplane when he hurdled two fences and 
made two complete short circles at the end of the 
field when he avoided a fence after a beautiful 
flight across the race track. 

Post had never been up very high before, nor 
had ever made a complete turn. He is the latest 
Curtiss pupil. 

Eugene P]ly, Mars and McCurdy broke honors 
even, on Saturday, the 27th, Ely by flying the 
longest and the highest of any aviator during the 
entire meet and winning the trophy given by the 
Manhattan Beach Hotel for being the only aviator 
to fly over the bay to the hotel and alight on the 
beach, go in for his dinner and return to the 
field late in the evening. 



Company. A receiving apparatus was placed at 
the top of the grandstand at the track and a 
.sending ai>iiaratus was secured in the machine and 
placed just behind the seat. It weighed about 
2."> pounds. The sending of the message was 
done by J. A. D. McCurdy while in flight in his 
four-cylinder Curtiss machiue. Mr. McCurdy was a 
wireless expert himself and will be remembered 
as on* of the members of the Aerial Experiment 
Association. . '' 

BY J. A. D. M CURDY. 

"The telegraphic key was fastened to my steer- 
ing wheel and was easily operated. For a ground 
wire from the machine, we used a wire about 
50 ft. long, which, after I got well into the air, 
was thrown overboard and allowed to dangle be- 
hind the machine, with the one end fastened to 
the apparatus. The antena consisted of the guy 
wiring of the machine so that the whole system 
was very simi>le. I made certain definite signals 
(certain letters) which were easily iiieked np by 
Mr. Ilorton from his position on the grandstand. 
I flew away for a distance of about two mil(>s 
and circled at an elevation of about 700 ft. and 
within this distance the instrument worked ex- 
tremely well. So far as I know, this is the first 
time that such an experiment has been performed 
and now that it has been already done, it will 
probably be tried extensively by Governments 
abroad. Mr. Horton came up to Hammondsport 
from New York and he and I have been trying 
the wireless from the aeroplane here ever since, 
and have made very satisfactory tests."' 



Another chaptex i»i aerial achievement is lecoxded an the sending 



of tills wixelesfi message i^OTn an aeroplane. «^

Mars on this day hurdled all of the steeplechase 
hedges in succession in his aeroplane and also 
qualified for his aviator's license. 

On the early morning of the 27th he dropped 
into the Lower New York bay from a height of 
500 feet, in his eight-cylinder machine, and was 
rescued by the wrecker Hustler and taken into 
Seagate, L. I. The accident was due to a short 
circuit of the magnate, when the oil push rod 
came in contact with the cut-out. 

Mars started from Sheepshead I'ark. flew out 
across thi» marshes towards Rockaway. then turned 
and flew over the ocean, passed- in front of the 
Manhattan Beach Hotel, down past the lower end 
of Coney Island, at Sea Gate, then turned u|) the 
l)ay and dropped in the water between Swinl)urne 
Island and the Atlantic Yacht Club. Tli(> distance 
was about 8 or 9 miles. 

The same afternoon at the Sheepshead Bay meet 
he took Mr. Post's machine and made three flights 
of five kilometers each, which qualified him to be- 
come a licensed aviator. 

The closing day of the meet was cold and dreary 
luit the four thousand who braved the elemenis 
in hope of seeing some flying were amply repaid. 

Long cross-country flights by Ely and ilars were 
the features, although Augustus Post furnished 
further thrills about simdown, when in a closing 
flight he could not see a fence at one end of the 
field and landed astride it with slight damage 
to the plane. 

During the meet the aviators flew every day 
as scheduled regardless of wind conditions, and 
Mars who was at the track a week in advance 
of the opening of the meet flew every day for four- 
teen consecutive days regardless of wind or weather 
conditions.

W^IRELESS ON AEROPLANE* 

WITH A NOTE BY 

Capt. Geo. A. Wieczorek, U. S. A. 

THE question of whether or not wireless 
receiving set could be utilized to advantage 
on aeroplanes has been frequently brought 
up. So far as known, no attempt to use 
wireless in this manner has yet been made. At 
the Chicago automobile show a wireless system 
was installed in the army aeroplane which was 
used as an exhibit there, but it had never been 
operated during a flight. Successful results have 
been obtained operating a moilel dirigilile, steering, 
stopping, starting, etc., by M. O. Anthony, as 
has been previously described in Aeronautics. 

An inquiry was made by this magazine of 
Captain George A. Wieczorek, of the Coast Artil- 
lery Corps at Fort Terry, N. Y. In reply he 
says : 

"Having followed the progress of wireless pretty 
closely for the past eight years, it appears to 
me that it would be rather diflicult to get any 
I)racfical result on account of the proximity of 
the spark in the cylinders of the engine. You 
see. the constani discharge taking place would 
s(-t up a rattle in the receiver which would be 
practically continuous on account of the rapidity 
with which ihe exjjlosions take place. 

MAY GUIDE MACHINE BY WIRELESS. 

"I believe, however, that it might be possible 
to arrange an apparatus on an aeroplane and to 
iluis guide its movements from the ground some 
distance awav. In Cul)a several years ago I 
liad an apparatus set uji only a few feet from 
an engine which used an electric spark to ignite 
Ihe gas in the cvlinder and after a little practice 
I had no difficulty in reading signals from Key 
West, or, miles off. while the engine was running. 
'•An aerial for receiving could be easily and 
cheaplv rigged up on an aeroplane and the lead 
from it could lie run through the receiver and 
grounded on the runners or steel spokes of the 
wheels."

Exhibition Flying About the States. 

Warehouse Point. Conn., Aug. 17. — Charles F. 
Willard (CurtLs.s) made several flights here this 
day. 

Bradford. Pa., on August 23, saw good flying by 
Willard. The grounds were excetnlingly dangerous 
Mild the last flight ended in a damaged machine. 

(ireenfleld, Mass.. Aug. 27-20. — Willard filled the 
(ireenfleld date, with his large ("urtiss machine 
making four fine flights, flying each day. lie flew 
over the trees and the river and nearby settle- 
ments, and carried a passenger on two separate 
flights. 

Hartford, Conn.. Sept. 5-9.— The flying at Hart- 
ford was of the usual Wright efficiency and con 
sistency. and the meeting was entirely satisfactory. 
Frani^ "CofCyn filled the engagement witli loii-i ;iiiil 
interesting flights. 

Lincoln, Neb., Sept. 5-10.- -Arch. Hoxsey 
(Wright) endeavored to fill a most difficult con 
traci for flights between the hours of 1(» and 12 in 
the morning, as well as two hours in tlie after- 
noon. He found a small infleld of a half-mile 
race tracl< surrounded entirely by barns, grand- 
stands and trees, as a place for him to fly. In an 
endeavor, on the second day. to satisfy a large 
crowd, he went up successfully, luit in landing was 
carried over against a barn and descended some- 
wliat precipitately. Ho was not iniured. but the 
main planes of the machine were badly damaged. 

Minneapolis, Minn.. Sej)!. .T)-1I). — Conditions very 
similar to those at Lincoln were found here. How- 
ever, Iloxsey came on from Lincoln and flew, to the 
great satisfaction of all concerned, completing the 
engagement which was interrupted by Welsh's poor 
landing. The weather was bad and there was but 
three days of flying. .T. C. Mars represented the 
Curtiss type of machine. 

Milwaukee, Wis., Sept. 12-16. — Arch. Hoxsey 
pleased the crowds at Milwaukee, though handi- 
capped by poor grounds. He made a spectacular 
flight on the opening day, going up 800 ft., cut- 
ting figure eights, diving, etc., in a 20-mile wind. 

FLYING INJURE.S EIGHT SPECTATORS. 

The flight of Hoxsey"s Wright aeroplane at the 
State fair on Sept. 16 resulted in an accident in 
which eight persons, five women and three men, 
were injured. The machine swerved sidelong from 
its course above tlie racetrack and plunged into the 
crowd in front of the grand stand. 

The aviator was uninjured and the aeroplan(> 
was only slightly damaged. 

Parkersburg, W. Va. — P. O. Parmelee, a new 
Wright aviator, filled an engagement here between 
the 6th and 10th inclusive, as a part of a celel)ra- 
tion of a home-coming week. Upon arrival. Par- 
melee found that the small racetrack was not very 
adequate for flying, and he therefore selected an 
outside field for some work. This fact, however, 
did not prevent him from doing all of the flyiii'4 
vyithin the small track, with the exception of but 
one day. On the last day of the exhil>ition he 
flew down the Ohio River and out over the town, 
returning and landing within the small infleld. 
The Parkersburg committee wrote daily, express- 
ing their delight and wonder at the wonderful 
exhibition Mr. Parmelee was able to afford them. 

OTHER EXHIBITION FLIGHTS. 

Charles F. Willard filled dates at St. Johns- 
bury. Vt., Sept. 1."). and at Ilolyoke, ]Mass.. Sept. 
17-18. On Sept. 5-6 Eugene B. Ely flew at Kala- 
mazoo, Mich. Augustus Post was at Canton, N.

chine, which is e(iuipped with a Kirkham 25 to :U\ 
h. p. 4-cylinder motor, gave evidence of extraor- 
dinary speed. 

Chicago-New York Race. 

There are ten aviators officially entered for the 
Chicago i-'o.s-f-New York 'J'iiiies Chicago-New York 
race for the !|;25,0()(> prize r)etween the 8t!' and

The winner of the $25,000 will be the man who 
first arrives in New York, provided he is there by 
the 15th. Starts may be made any rim.e after 
sunrise on Octoljer Sth. 

-Vt Chicago, from the 1st to the 7th inclusive, 
exhibition flights will bo conducted by the Chicago 
Evenuiti /'o.st, in which the competitors in the race 
itself are required to take part. The aviators 
will l>e given a percentage of the gate receipts. 
Th(> first two days are open to anyone, but the 
remaining ones will be devoted to the flights of 
only those who are actually starting m the race. 
Sixty per cent, of the proceeds from these exhibi- 
tions will l)e given the aviators taking part in the 
race itself, as follows : The aviator who reaches 
Xew York first or the nearest point to New York 
in the time set for the race, will receive of tliis 
t;n per cent, a share amounting to 40 per cent. ; 
(he second l)est man gets 20 per cent.; the third, 
15 per cent., and the remaining 25 per cent, is 
divided pro rata among other contestants, with 
the provision, liowever, that no one of these •"also 
rans" shall gel more than the 15 per cent, allowed 
the third man in the race. 

International Aviation Tournament. 

Arrangements for the international aviation 
tournament, October 22-30, have at last assumed 
definite form, and energetic effort is being made 
to make the big meeting at Belmont Park the 
most succes.sful event of the kind ever given in 
.Vraerica. 

The subscribers committee has raised about 
^:125,()IM> in popular subscriptions, and both the 
funds and the general business management of 
the meeting have now been turned over to the 
.\ero Corporation, Ltd., which in turn has named 
several committees to take charge of the general 
work of organization. Allan A. Ryan is made 
chairman of the committee on arrangements and 
becomes the nractical business head of the meet- 
ing. J. C. McCoy, as chairman of the committee 
on aviation, has charge of the programme, pro- 
curing of the aviators and all things that pertain 
to the sporting phase of tlie tournament. 

Cash prizes to the amount of .$5(i,0(Mi are offered 
and in addition to this a protit-shariug arrange- 
ment has been decided upon whereby tlie aviators 
will get a large part of the net receipts of the 
meeting after deducting the necessary expenses. 
I'nder this arrangement the aviators will receive 70 
per cent, of the first .$100,000 net profits, and 40 
per cent, of all sums over that. The managers 
are assuming that with good weather and normal 
attendance there will be something like .$200.ooo 
to be divided among the aviators under this plan. 

General liusiness lieadquarters of the tournament 
have l)eeu opened in the Fifth Avenue Building 
at Fiftli .Vvt^nue and Twenty-third Street, and a 
force of experts and clerks are at work tliere put- 
ting tilings into shape. 

Belmont Park is undergoing such transforma- 
tion as is necessary to make it suitable for the 
airmen and the big crowds. All obstructions have 
l)een removed from the infield where a two-and-a- 
half kilometre course is being laid out for the 
general events. .\ five kilometre course for the 
Gordon Bennett trophy race will extend outside 
of the park to tlie east, l>ut the start and finish 
of all events will take place directly in front of 
the grandstand. 

The (iordon Bennett international race, which 
will doubtless be the banner da.v (if the meeting, 
will occur on October 21). and the elimination 
trials for tlie selection of the American team will 
probably take place October 26. Coming as it does 
after the close of all other meetings here and 
aliroad. it is expected that the list of entries for 
the .foO-OOO prizes will be large. Nearly two 
montlis before the opening of the meeting, it is 
said by the management, that applications had 
be(m rec(Mved from a larger number of foreign and 
.\mcrican aviators than have ever appeared at any 
.\.m(>rican meeting, and liy October 15. it is expected 
that the aviation committee will be able to close 
its books with as interesting a list of airmen as 
have ever appeared at any one meeting. 

For the Gordon Bennett contest France has al- 
ready named Alfred Le Blanc, Hubert Latham

Lamson Issues Notice of Infringement. 

Becker & Hlakcslee, attDrncys for Charles II. 
Ivamson, of I'asadena, Cal., have sent out a letter 
to various makers aud dealers iu aeroplanes, de- 
manding that the recipients cease making, selling 
or using flying machines. The principal claims of 
the patent, witli drawings, were printed in the 
July, 1910, issue of AERONwrTics. The letter fol- 
lows : — 

"This is formal notice to you of the 
issuance of Letters Patent of the United 
States, number (>6G,427. dated January '22. 
190], to Cliarles II. Lamson. which said 
letters patent you are infringing, in 
making, using or selling flying machines 
or mechanism or apparatus for navigating 
the air. We are directed by Mr. Lamson, 
tlie patentee, to demand of you and your 
agents, attorneys and servants, that you 
and each of them cease and terminate 
any such act or acts of infringement of 
said letters patent, or acts of infringe- 
ment of said letters patent of any nature 
whatsoever, and that you and each of 
tliem respect said letters patent and tlie 
monopoly and rights thereby granted and 
awarded to said patentee. Suit for in- 
fringement of said letters patent is now 
pending against the Wright Company, of 
Dayton. C)liio, and furtlier suits for in- 
fringement of said letters patent will in 
due course of time be instituted against 
other infringers; and the court will l)e 
asked to cn.join any sucli act or acts of 
infringement, and to award to said pat- 
entee the damages and profits involved in 
aud flowing from any such act or acts of 
infringement, and to grant such further 
relief as may in eaeli instance be proper 
and warranted by the facts. 

"Pending adjudication upon said letters 
patent, and in order that no person, firm 
or corporation engaged in truly promoting 
tlie .sport and art of aerial navigation may 
be barred or interfered with in such 
(>fforts. we are prepared to issue proper 
licenses covering tlie manufacture, use, 
sale aud attendant activities involving the 
use of the invention covered by said let- 
ters patent. Tlie initial payments on ac- 
count of royalties or license fees in con- 
nection with the issuance of such licenses. 
will be nominal in each instance : and the 
payment of the balances on account of 
such license fees and royalties will be 
made conditional upon such adjudication 
of said letters patent as shall amount to 
a determination of the validity thereof." 
"Very respectfully. 

"Becicer & BLAKESr.i;K. 
"Attorneys and Counsel for Chas. H. Lamson." 

National Council of A. C. A. Issues By-Laws. 

The National Council of the Aero Club of Amer- 
ica has issued its first booklet. Full details of 
the organization of the Council have already been 
given in Aeronautics. 

The clubs now belonging to the National Coiuicil 
l)ay .$:;."( a year dues and .$1 for each member. New 
clubs joining the Council must pay an initiation 
fee of ,$50 and ,$1 for each member. Though, if 
admitted between .January 1st and July 1st. the 
rate is but 50 cents for each member. 

It seems more than ever ai)parent that the whi|i 
hand is with the Aero Club of America, as one of 
its oflicers announced at th(> tinn^ of the formation 
of the new body. The by-laws provide that the 
chairman of the Executive Committei' be named 
bv the Aero Club of America, and in addition, the 
Clnl) has the privilege of naming another voting 



reiiresentative ; the otlier tliirteen composing the 
I^xecutive Committee being made up of the other 
members of the Council. The Executive Committee 
has complete control of affairs between semi-annual 
meetings of the Council, and the chairman exer- 
cises executive powers between meetings of the 
Executive Committee. 

Following out the up-to-tlie-present-existing pol- 
icy of the Aero Club of America, to have the whole 
say so far as possible in matters aeronautical, the 
lilan of the National Council is to have but one 
elub in each State a member of the Council ; that 
club in turn to have afliliated with it the local 
rlubs of its State. The exception is made, how- 
cn^er, of the clubs represented at the organization 
meeting. As many clubs in one State or Territory 
as were represented, are now members of the 
Council. 

Th ^ Contrst Committee has made out a very 
comr' 'e s( t < I conditions to be observed by those 
proni/'ng r 's. though there is no case on record 
where these I've been complied with as yet. One 
particular rule of interest provides for the )>re- 
venting of any performance by a contestant refus- 
ing to conform to the rules and regulations of the 
National Council, and the inflicting of penalties 
and disfiualiflcations. 

The Contract and License Committee is to keeji 
in touch with the qualifications of all professional 
and amateur aeronauts and aviators and to seek 
to induce them to apply for pilot licenses. 

The Academic Committ((< is supposed to be con- 
versant with the work done by the various gov- 
ernments, schools and laboratories, and to co-oper- 
ate with educational authorities "with nower to 
recciv(> donations and confer medals." The Aero 
Club of America has always been gratifyingly 
active in the awarding of medals, certificates of 
merit, the holding of banquets and particii)atini; 
in other strenuous labors. Perhaps the most im- 
portant committee is the one on publicity, among 
whose duties is the furnishing of news items to 
the press. 

Every affiliated club is entitled to one voting 
member in the Council, though another representa- 
tive is provided for and allowed the privilege of 
attendance at all meetings and the riglit to debate 
l)ut no vote. 

T^romoters of meets or exhibitions are asked to 
]iay a fee of .lilOO to cover the first two days of 
tile meet and .$50 for each additional day. 

Wheels on the Army Aeroplane. 

Through the kindness of General James .Vllen. 
Chief Signal Officer of the Army, we are able to 
furnish some interesting details of the wIk'cI ar- 
rangement on the Army aeroplane. 

Tile original idea in equipping tlie macliine with 
wheels was to employ a system whereby tlio 
wheels would be used for starting and lioth skids 
and whe(>ls would be used in landing, thus minim- 
izing the amount of reconstruction of the under 
structure of the macliine. and reducing the wear 
and tear upon both wheels and skids in landings. 
This idea has been carried out with but sliglit 
modification and the results have been entirely 
s itisfactory. Five wlieels 14 in. in diameter are 
used. Four wheels in pairs under the machine 
(one pair for each skid), and one wheel in front 
to support the weight of the machin(^ in fr(nit of 
the main planes. All wheels have th(> same di- 
mensions, are interchanaeable and are ecpiipped 
with steel rims and 2iA in. single tube fires. 
Each pair of wheels under the machine are oper- 
ated on a steel shaft 12 in. in length, connecting 
its two wheels. This shaft rests on toil of the 
skid, and is held down in place by means of a 
vertical wooden block and two vertical tension 
springs. .Vcross the top of the wooden block is n

Gentlemen : 

Yours of the 26th inst. received, and m reply 
will say, that we have secured a 260 lbs. thrust 
with your propeller at 1,400 R. P. M. 

1 have made several short flights with the pro- 
peller, the longest being 200 feet, when I met 
with an accident which the enclosed clipping 
will explain. I then wired you an order for a 
7 ft. propeller. 

I can honestly recommend your propeller to 
anyone wishing to secure an efficient propeller, 
and take pleasure in giving you this testimonial. 

Very truly yours.

flat steel rod with ends turned up into whicli 
ttie ends of the springs are fastened. The other 
ends of the sin'ins's arc fastened to the sl^id by 
means of metal bands. The two vertical springs 
and wooden block are enclosed within a .ight 
galvanized iron casing to prevent the springs and 
block from distortion due to lateral strains. In 
addition to the heavy vertical springs, four hori- 
zontal springs are employed to minimize the 
horizontal torque on the wheels resulting while 
running on the ground. These springs are at- 
tached to the shaft so that one pair exerts tension 
to\\ard the rear, while the other pair opposes this 
tension. The single wheel in front is provided 
-with two pieces of flat spring steel which constitute 
a fork for the wheel. The pieces of spring steel 
are fastened to a cross bar and guyed in four 
directions with steel wire to prevent movement in 
any direction. These i)ieces of spring steel are 
designed to support a weight of about 80 pounds 
under a 7 incli deflection. This weight being suffi- 
cient to force the skids to the ground. The op- 
eration of the machine as regards the use of wheels 
is as follows : 

With the engine running and the machine held 
stationary, the front end of the skids are forced 
to the ground, due to the high thrust of the pro- 
pellers. Upon releasing the machine it moves for- 
ward slowly lat first. As soon as the front plane 
is elevated, the air pressure under the elevating 
plane raises the front skids and allows the front 
wheel to do its work. As soon, as the momentum 
of the machine, increases the weight of the ma- 
chine upon the vertical springs decreases until 
finally all thi- wlieels lea\-e the ground. T'pon 



The Latest Gill Biplane. 

The Howard W. Gill Curtiss type biplane which 
made its first appearance, with successful flights, 
driven by a stock 26 h. p. automobile engine, at 
the Los Angeles meet, has been taken over by the 
St. Louis Aeronautic Supply Co. 

The later type Gill machine, on Farman lines, 
and without any front rudder, has started on an 
exhibit i(in career with Hillery Beachey as aviator. 

The vertical control of the Gill biplane differs 
from other biplanes by its location in the rear 
of the machine, where it also acts as a steadying 
plane as well as an elevator. 

As will be seen from the drawing it consists 
of two .'superposed planes which are pivoted slightly 
in front of their center of pressure^ about one- 
third of the distance from the front edge, both of 
which i)lanes are connected front and rear by up- 
riaht wires so that they work in unison. 

To give added security the wires controlling the 
elevator are in duplicate and besides a safety wire 
is also iilaced in the rear plant. As these "planes 
are hinged forward of their center of pressure 
should anything happen it would have the sarnie 
effect as the operator taking his hand off the 
controlling lever in which event the rear planes 
would point down and start the ship climbing- 
upward, in this case the safety wire comes into 
effect and only allows the machine to climb at a 
safe upward angle, so that by slowing down the 
motor the machine can be brought naturally and 
safely to the ground. 

A landing of this nature was made necessary 
in the experimental sta^^es at Los Angeles, Cal.,

landing, the machiae is guided so as to land upon 
me Hunt wii: el. Lender the force of impact the 
front wheel is deflected upward, allowing the 
skids to strike the ground. The pairs of wheels 
under the machine as they strike the ground are 
forced upward, allowing the skids to strike the 
ground. The reaction of all the springs after the 
initial impact raises the machine and allows it to 
run along the ground until it comes to a full stop. 

One of the most unpleasant features in landing 
on wheels is the difliculty experienced in stopping 
the machine after landing. This is extremely vital, 
particularly when landing in a small enclosure. 
This difliculty has been practically eliminated by 
means of the' flexible front wheel and the use of 
the front elevating control. Upon striking the 
ground the front control is depressed, the air 
pressure on top O'f it being suflicient to hold the 
skids on the ground, thus bringing the machine 
to a full stop in nearly the same space as was 
formerly the case when using the skids alone. 

During the month of August Lieut. Foulois made 
several short flights, aggregating in time T-") min- 
utes and 43 seconds. These flights were merely 
experimental, and for purposes of testing out the 
new system of control and the new system of 
wheels. 



through a broken wire, and was made without any 
breakage to the machine, and in such a natural 
way that those who witnessed it were unaware 
until told. 

A hand-lever placed on. the right side operates 
the vertical control. A forward movement in- 
creasing the angle of incidence in the rear tail 
which raises the tail and steers the biplane down- 
ward. Pulling back on the lever reverses the' 
movement and steers the machine upward. This 
same lever also controls the ailerons. At first 
it was hinged in a universal .joint to secure both 
the forward and sideway motions. This was after- 
ward changed to the T-joint shown as it was found 
to give a better control than l)y pivoting the 
lever on a univmsal joint. In the improved .1oint 
both the forward and sideway movements are more 
l)ositive and distinct. With this new typo lever a 
movement of the ailerons can be made without 
any tendency to work the eli^vator also, or vice 
versa. 

At first the rear elevator was found to have 
a decided lag. a movement to raise tlie ship would 
apparently have no effect, which madi- the operator 
feel that the lever had not l)een moved sufficiently 
to raise the machine and generally resulted in and 
increased movement of the lever then as tlie flyer

would start rising duo to the first movement the 
lever would bo pushed forward to carry the machine 
level when on. account of the ship still rising it 
would seem as if it was beyond control. By in- 
creasing- the surface of the roar tail and reducing 
the weight this lag. nearly always apparent in an 
aeroplane controlled vertically from the rear, was 
to all practical purposes eliminated. 

As it is necessary for good stability to have a 
machine with a rear plane it is a big advantage 
to use this tail as an elevator also. To leave off 
the front elevator not only makes a lighter machine 
by some 40 to Sd pounds, but makes the rest of 
the ship stronger by its not having to stand this 
added weight, on account of their being no ol) 
struction in front. In case of an accident the 
operator is less liable to be caught under the ma- 
ciiine and crushed. It is bound to make a faster 
and therefore more stable flyer by the elimina- 
tion of the head resistance of the front planes 
and their supports. 

Wellman Airship. 

Rapid progress is being made toward the prep- 
aration of the Wellman airship "America" for 
its promised attempt to cross the Atlantic. Since 
the last start for the pole on August 15. I'.JIO. the 
airship has been enlarg<'d and improved and an 
entirely new steel car placed under it. It is an- 
ticipated that the voyage across the Atlantic will 
require from six to ten days, depending on the 
force of the prevailing winds. 

Trials will be made at Atlantic City in which 
the e(iuilibrium will not be used, sand and water 
ballast being employed instead. These trips are 
to test the machinery and get everything in run- 
ning order. 

The ^'America" is the second larg;est airship 
over built, and next to the Zeppelin in size, but 
has a larger carrying capacity than the Zeppelin. 
Tile ship has been built and perfected in Paris 
under the direction of Walter Wellman. and the 
personal supervision of Chief Engineer Vaniman, 
, who designed most of the ship and constructed 
many parts and accessories. 

FACTS ABOUT THE AIRSHIP ^'AMERICA.'' 

Length of Balloon 228 feet. 

Greatest Diameter 52 feet 

Volume ;}45,00O cu. ft. 

1 cubic foot of air weighs 11/5 oz. 

."45. 000 cubic feet of air weighs 
25,800 ])(>unds. 
The l)alloon is inflated with hydrogen gas gen- 
erated by using eighty tons of sulphuric acid and 
sixty tons of iron turnings. The gas is washed 
and dried to make it as light and pure as possil)lo. 
This gas weighs one-tenth of an ounce per cubic 
foot and the .".45.000 cubic feet required to All 
the balloon weighs 2.150 pounds, the gas being 
twelve times lighter than air. The lifting force of 
I lie balloon therefore is the difference between the 
weight of the air displaced and the weight of the 
hydrogen with which the balloon is fllled. The 
total lifting force of the "America" is 23.G50 
pounds. 

The balloon itself, composed of three thicknesses 
of cotton and silk gummed together with rubber 
to make it gas tight, weighs 4,850 pounds. Un- 
derneath the balloon is suspended by steel cables 
the car. which weighs 4.40O pounds. This car is 
l)uilt of the highest grade steel tubing and in 
places withstands stresses of twelve tons. 'I'ho 
car is 150 ft. in length, and the steel tank at 
its base is 75 ft. long with a capacity of 1,250 
gals, of gasoline. The engines, three in numher. 
(two of 80 h. p. and a service motor of 10' h. p.) 
arc placed in the stool car. P^ach of the large 
motors drives a pair of twin screws, and each 
propulsion system is indoijondont of the other. The 
motors and other machinery weigh about 1.5<I0 
pounds. Sleeping (juartors arc provided the crew 
of six men in the triangular parts of the car. 
An electric light system, a wireless telegraph 
equipment and a telephone connecting the different 
parts of the ship are being installed. 

A specially built life-boat, constructed in Eng- 
land, will be swung underneath the car, fully 
equipped with provisions, water and instruments to 



be used by the crew in an emergency. This life-boat 
weighs less than 1,000 pounds. 

Hanging from the airship by a strong steel 
cable is what is known as the "equilebrator," a 
part of which will float upon the surface of the 
sea, the other being suspended vertically in the 
air. The purpose of this is to act as an auto- 
matic regulator of the upward and downward 
movements of the airship. When the ship rises, 
it must lift some of the eciuilebrator from the sur- 
face of the sea in order to go up. and this added 
weight checks the rising movement. Conversely, 
when change of temperature or accumulation of 
moisture causes the airship to descend, a greater 
part of the equilebrator is let down upon the sea, 
thus reducing the weight carried by the balloon 
and checking the descent. The equilebrator is 
composed of thirty steel tanks containing gasoline 
and strung together by a strong steel cable. The 
gasoline thus carried is a reserve supply for the 
engines. 

The total supply of gasoline carried will l)o 10.- 
000 pounds, or about 1.800 gallons, which is con- 
sidered sufficient to drive the airship from Atlantic 
Cit.v to Europe. The distance is about :j,000 miles. 
With one engine running, the airship will have a 
speed of twenty miles per hour, and the quantity of 
gasoline carried would run one engine 200 hours. 
With both engines running, the ship's -speed in still 
air will be about 26 miles per hour.

Philadelphia Aero Show Changes Date. 

'I'he arrn show which has been announced by 
the -Vi ro Club of I'ennsylvania. to l)e held in the 
First i4egiment Armory. Philadelphia, has been 
|)ostponed a few days and will now be held No- 
vember 1! to 12. 

This postponement has been found necessary be- 
cause a number of the aei'oplanes which will be 
on. exhibition and which will be the principal at- 
tractions for the public will be competitors in 
the P.elmont I'ark meet, and as these races have 
been put off until October 22 to 29, the arrange- 
ments have been made to oijen the show on the 
Wednesday following, thus siving plenty of time 
to ship the machines from Long Island to Phila- 
delphia and to set them up in the Armory. 

In response to a number of requests from ex- 
hibitors W'ho are also going to show their goods 
in St. Louis, the .\. C. rf P. is arranging to have a 
special car engagcn] to be jiacked with goods from 
the Philadelphia show juunediati'ly on the close. 
November 12, and to send this car by express to 
St. Louis, so th;it the exhibit can be set up thiM'e 
In time for th(> oi)ening. 

The Philadelphia show is attracting unusual in- 
terest among dealers in aeronautic and aviation 
supplies because of tlie activity that has been 
recently shown by the Aero Club of Pennsylvania. 
This organization has now gone Into ballooning 
with weekly asccnits scheduled. Its new grounds 
for aeroplane flights at Clementon. N. .1.. have 
been pronounced by those who have seen them 
to be far ahead of most other grounds, both in 
their natural advanta,ges and In the buildini which 
has been doue on them. 

The hangars on these grounds are three liun 
dred feet long and so constructed that there arc- 
six separate compartments, each 50 ft. wide and 
40 ft. dee)), and each containing a work-bench and' 
two sleeping compartments, to accommodate four 
persons. The club Is also Installing a complete 
machine shop to be run by a 5 h. p. gas engine, 
and the fact that every one of these hangars has 
already been leased for the entire winter is an 
indication of the busy days that are in store for 
members of this organization. 

.V large ))ercentage of the space in the Aero Show 
has already been taken by residents of eastern 
Pennsylvania, Southern Xew .Jersey and Delaware, 
of which Phihidc^lphia is tln^ natiu'iil center, these 
residents having turned in remarkable numbers 
to the manufactnr(> and sale of aeronautic and 
aViation g(jods. The recent growth of the .\ero 
Club of Pennsylvania has been one of the most 
notable features of American aviation news and 
the club Is being run upon a business basis which 
promises well for Its future. 

The "Three States Aero Show" has lieen i)Iace<l 
by the club under the management of Henry M. 
" Xeely, the secretary, who is also chairman of the 
committee oa contests and exhibitions, and who 
has had many years' exiierience in show manage 
ment and publicity. 



St. Louis National Aero Show. 

Preparations for the St Louis National Aero 
Show, to be held .November IT to 24, in. the great 



Coliseum In St. Louis, under the auspices of the 
.Vero Club of St. Louis, are rapidly progressing. 
The manager now believes there will be on exhibi- 
tion from 12 to 15 full size aeroplanes and 40 
or 50 flying models. 

More than 35 concerns have already contracted 
for space at the show, among these are : 
AEKONAriTics. Detroit Aeroplane Company. Aero- 
nautic Supply Company, Goodyear Tire & Rub- 
ber Company, Aeromotlon Company of America. 
.Verial Navigation Company of America, Leading 
Brass Company, French-American Balloon Com- 
pany. Missouri Stair Company, St. Louis Pattern 
& Model Company. LTnited Storage & Battery Com 
pany. Lawson Publishing Company, Phoenix Auto 
Supply Company. Western Oil Pump & Tank Com- 
pany, (>. K. Harry Steel Company, Erker Bros. 

.Vmong the complete aeroplanes to be shown will 
be a Wright machine which will occupy the place 
of honor at the main entrance, a Farman biplane, 
a Santos lunnont "r)emoiselle," Gill biplane, Cur- 
tiss biplane. Baldwin biplane, and several other 
machines that have recently tried out, but have 
not yet made important flights. 

.\ novel exhibit will be that of the Missouri 
Tent & Awning Company, makers of aeroplane 
hangars, which will show a model aviation field 
with a miniature grandstand, hangars and aero- 
planes. .\mong the flying models there will be a 
novelty in the form of a oruithopter, which actu- 
ally flies in much the sam(> way as a humming 
bird. 

The spaces devoted to the exhibits of Inventors 
or those who will show plans, or specifications, 
or models of .(ircraft, in which they jleslre to 
Interest capital, arc rapidly filling up. 

G. L. Ilolton. manager of the show, with offices 
in the Coliseum building, reports that there is 
very little space left in the Coliseum and urges 
manufacturers who plan to exhibit there to advise 
him at once. 



BALLOON TRIP OVER ROME 

(Coulinued from page 111) 

I was seven hours on my voyage from Kome 
to Benevento. .going over the Apennines, where I 
was well received by the Italians, who praised me 
very much, because I had courage to defy the I'ope, 
who then had a bitter feeling for some cause 
against our nation. Several j)ersons hailed me 
on my way. and were highly delighted to see a 
great balloon pass over their heads. I made the 
voyage of two hundred miles In the year ISK!* 
from Rome. My American and English friends 
)H-esi'nted me with a splendid flag in Uome. wliicii 
they desired to st>e me wave over the city. 

\t that time only the Pope's flag was allowed 
to fioat over the Eternal City, by orders of the 
Pope (Pius the Ninth) who reigned over the city. 
His secretary. Antanelli, and (iovernor Kandl. said 
I must not carry the Stars and Stripes over Rome. 
On my third ascent I put my flag in the car. and 
as I began the ascent I took off the Pope's flag 
and i)ut in its place the Star Spangled Banner and 
waved it in triumph. A tremendous shout from 
.\mericans and British and the admirers of Gari- 
baldi was given as I sailed off towards the beauti 
ful city or villa of Tivoll at the foot of the splen 
did Apennines. 

I had to give away half the money received at 
the villa of Borghese, an Immense garden belong- 
ing to Prince Borghese, who married Pauline, the 
sister of Xapoleon'the (Jreat. .\l>ont four thousand 
dollars was taken at the gales. Garibaldi and 
Crispi were my friends, and seemed highly de- 
lighted with my courage and defiance of the Pope 
and Roman powers. 

At Naples I jTceived n,., liiteenth degree in Free^ 
unisonry at the (iariUaldi lodge. In the masonic 
lodge at Palermo, where M. Crispi was the grand 
master of the lodg(\ I heard him and others speak 
in favor of taking Uome bv Garibaldi. The poet 
Longfellow and tile (,)ueen of Naples were among 
the twenty thousand people who saw my ascent 
at Rome.

of 60-75 or even more horsepower, the Detroit 
Aeronautic Construction Co. is contemplating put- 
tins? on the marl^et an 8-c.vHnder engine. Tlieir

weighing conii)l('t(' aliout llS.'i lbs., rated at »)'0-7,") 
h. p. 

Bosch Chicago Office Moved. 

The office and headquarters of the Chicago 
branch of the Bosch Magneto Company has re- 
moved from the former address at 12.">:!" Michigan 
-V venue, to 119-]L>1 East 24th Street. A two-story 
building midway between iMichigan and Indiana 
Avenues. 

Demountable Rims for Aeroplanes. 

'I'lie Dorian Itemountalile Itim Co. has brought 
out a demountable aerdplane rim. The principle 
of the construction and ojun^ation of the aeroplan<' 
rim is the same as that of the automobile rim, the 
chief difference being that the felloe band of the 
automobile rim is shrunk on the wood felloe of the 
automobile wheel, while with the aeroplane rim. 
the wire spokes of the wheel are secured in the 
joint as per the general practice. 




'l"he five wedges of the aeroplaui' riui are made 
of aluminum alloy, and the rims on which the tir(> 
is lifted is of rolled sheet aluminum : the felloe 
band is of steel. 

The difference in weight between the rim and 
a regular clincher rim is about .5V^ pounds per 
wheel. 

To remove the rim with the deflated tire so that 
the rim with a iiroperly inflated tire can Ite lifted 
in its place, it is necessary to merely remove three 
of the wedges by turning the nut "■B," which is 
held in thi' wedge by a plate so that it virtually 
forms part of fhe wedge ; for this reason, it is im- 
possible to lose a nut. The band to which the 
spokes of the wheel are secured is made of an 
alloy steel, and the rim holding the tire is made of 
steel aluminum alloy rolled to shaiie. 

On Two-Cycle Engines. 

At last even conservative Mineola, the hotbed 
of aviation in the East, has comi' to accept the 
two-cycle engine of modernized type as one solu- 
tion of the iiower problem for consistent aero- 
nautic work, and none of the novice aviators 
there feel their chances for achievement are good 
without the now popular two-cycle engine. 

In the Western States they found favor months 
ago. because Western users of gasoline engines 
know that all (heir fastest motor bouts for I In- 



past two or three years have been driven by light- 
weight two-cycle engines. And the winning of a 
great motor boat even demands from the power 
plant .lust what successful flight calls for, — an 
engine very light for its power, very simple in 
design, and one capable of turning a proi)eller 
at a high speed for eonsidei-able periods of time. 

Autoimobile work is entirely different ; the motor 
must jiull hard in starting or climbing hills, but 
runs i)ractically free on level ground, — except 
where extreme high speed is maintained. Prac 
tically no "stock"' automobile motor will stand 
maintained high speed ; it overheats, connecting 
rod bearings pound to pieces, or, most frequently, 
the valves wari) and fail. The motors simply 
are not designed for indefinitely long runs at max- 
imum speed, consequently no really successful 
flight has been made in America with an autcmo- 
bile engine. Two-cycle motors have been success- 
ful in motor boat work simply because they have 
been designed and perfected with but two ends 
in view, power for weight and long continued high 
speed. 

Mineola, however, knew little about boats or 
l)oat engines. ^Most of the men who formed the 
colony were graduates from the automobile school 
and they were sceptical concerning the alleged 
merits of the two-cycle engines. 

"Xothing to it," they said at first, and then 
lir. W. (Jreene made a couple of get-aways early 
in the season. 

Dr. (ireene's flights proved that the engines 
would fly, so Mineola had to leave the general 
and come to the particular. 

"Two-cycle engines are difficult to start, "" said 
the "boys"; but G. E. DeLong brought his Schnei- 
der ■plane to ^lineola with an Elbridge two-cycle 
engine, started it in two minutes the first time 
and on the spark whenever he liked for th(> rest 
of the day. The doubting Thomases were begin- 
ning to scratch their heads. 

"But you can't keep a two-cycle engine^ cool 
with an ordinary radiator," they exclaimed, when 
a iMMi. 1). radiator attached to a .")0-h. p. engine 
boiled over after a ten-minutes'' run. Two or 
three days later .1. .1. Frisbie installed a four- 
cylinder Elbridge in his 'iilane. used two small 
radiators so placed that they received an unin- 
terrupted current of air, and not only did the 
two-cycle engine cool properly, ))ut it was the 
only engine on the aviation field that could be 
run for twenty minutes at a stretch (standing) 
without boiling over. 

"That's a nice little engine," said Captain Bald- 
win to Frisbie, when the installation had been 
made and Frisbie was preparing for his trial 
flight, "but a man needs more power to fly with 
than you can get from four small cylinders." 

"(ireat Scott ! That's too much i)ower for a 
novice to monkey with," said Captain Baldwin 
five minutes later, as F'risbie sailed by at a speed 
approximating fifty miles an hour. 

"Anyway, you can't throttle down a two-cycle 
engine." was tlieir final wail, quite refuted by 
different users, who throttled down the engines in 
tbeii' machines so well that the 'planes could be 
left standing alone with their propellers slowly 
turning. 

That was the last straw, ami fhe crowd bolted 
for two-c.vcle engines of the "Featherweight" t.vpe. 
(Jeorge Russell, who has been using a four-cycle 
engine all summer installed a two-cycle and went 
away to fill an engagement. Frisbie. in three 
weeks, had learned to fiy so well that he threat- 
ened the laurels of men who have siient mor(^ 
than months learning to fiy, and he found I'asy 
money reaching out to him. Some half-dozen 
others followed suit, until now there are more of 
one make of two-cycle engines being installed at 
Mineola than all ditt:'erent four-cycle makes com- 
l)ined. 

There now are literally dozens of them around 
New York. Their chi(>f beauties seem to be 
strength, power and smooth-running. They have 
been in smash-ups of all kinds, but not a part of 
nii\- one of the engines has bi'en broken. Several

men report leaving the grouud inside of 100 feet, 
wliicli speaks well for their reserve power, and in 
summing- up the operation of the engine the 
Ercniufi Sun of August ."iO says it "runs like an 
electric motor." 

At Buffalo on Labor Day an Elbridge "Feather- 
weight" installed in. the boat Elbridge V, won the 
1500 Buffalo Launch Club trophy for the 25-mile 
championship of the Tireat Lakes, under condi- 
tions so adverse that none of the other boats, 
mostly equipped with four-cycle engines of 250 to 
300 h. p., finished the race. 

Kven Europe has fallen victim to the seductions 
of the simple two-cycle engine, there are several 
new makes on the English market, and the Amer- 
ican manufacturers of the Elbridge "Feather- 
weight" engines are said to have declined to enter- 
tain a proposition guaranteeing $."111.(1(10 per year 
for Kur()])o;m manufacturing rights. 

Finest Workmanship Displayed on Burgess- 
Curtis Biplanes. 

The Burgess Comiiany •& Curtis has good reason 
to be gratified l)y the many compliments the ma- 
chines received for their construction and un- 
equalled finish. Several of the aviators at the 
Bo.ijton meet have requested this concern to furnish 
fhiui with spare parts or construct machines for 
tlicm. The new 8-ft. propeller designed by W. 
Starling Burgess has attracted particular attention 
ever since it developed a thrust of more than 4G0 
pounds. Wliile the power to produce such an enor- 
mous thru.st was primarily due to the excellence 
of the eight-cylinder Indian motor, it is neverthe- 
less greatly to the credit of the propeller itself 
that the power should be applied so efliciently. 

IMPORTING CLEMENT MOTORS. 

The Clement-Bayard motors, which this company 
is importing direct from the manufacturer, can be 
supplied at .fl.SOO each. These motors when 
tested by Bleriofs engineers developed from 25 
to 31 h. p. continuously and weigh less than 110 
pounds. The well-known reputation of the Cle- 
ment-Bayard factory is back of them. 

The Burgess-Curtis machines at the Boston meet 
did not show up so prominently for unavoidable 
reasons. A (?0 h. p. motor for tlie Burgess biplane 
owned by Messrs. Shoemaker and Hilliard arrived 
only at the last moment before the meet, and Mr. 
liilliard has rc(iuired a largo amount of testing 
and adjusting in order to adapt the heavy motor 
and its ,8-ft. propeller to a machine designed for a 
light 25 h. 1). motor using a G-ft. propeller. Then, 
again, the Clement-Bayard motor for the Model C 
inarliine arrived only the very day on which the 
-Mixicl C was shipped to the aviation field. There 
wfvr many delays in getting the motor set up and 
properly provided with radiator and other acces- 
sories. 

In view of tli(> fact that the company has not 
yet succeeded in securing the services of an ex- 
perienced aviator, Mr. Burgess recently decided to 
undertake flying one of the Model B machines him- 
.self. He has shown considerable proficiency in 
making short jumps on an even keel, but as he 
keenly realizes that any damage resulting to the 
machine from faulty handling on the part of the 
aviator would l)e attributed by the public to faults 
in the biplani' itself, he is pursuing a conservative 
policy and making ])rogress slowly. 

Goodyear Four-Inch Tires. 

Large size tires are coming more into favor, as 
they deserve. They ride holes and ruts in fields 
where .small tires catch and buckle the wheels. 

The Goodyear Tire and Rub1)er Co. is now mak- 
ing 20x4-in. detachable and 20x2-in. single-tube 
tires, and expects to increase its facilities in this ' 
line .sliortly. 

The Anzani Aviation Motor. 

The .^-cylinder Anzani motor, which, since an 
agency was started in the I'nited States, has 
already sold well, is made in five sizes, ranging 
from 10 h.p. to 45 h.p. Specifications of these 
motors follow here below. 

The cylinders are radially disposed and are 
placed at an angle of approximately 00 degrees. 
Assuming that the cylinders are numbered one, 
two, thriM'. the explosions will take ])Iace first in 
numlier one cylinder, thru in niunher three and 



finally in number two. This distributes the ex- 
plosions evenly over the circumference, which in- 
sures almost perfect balancing of the engine. The 
cylinders are cast in steel separatelv, the valve 
chamber being solid with the chamber wall. 

The valves are of the well-known mushroom 
typo of nickel steel ; the inlet valves are oper- 
ated automatically and are situated at the top of 
the cylinders, while the exhaust valves are lo- 
cated at the side of the cylinders and are oper- 
ated from a single timing gear. 

The air cooling as used for the Anzani motors 
has proved very efficient. As the motor runs all 
the time at top speed a tremendous circulation of 
air is obtained, which insures perfect cooling. 
Even if the motor is installed in the rear of the 
machine, the suction caused l)y the propeller is 
sufficient to create a draught, which in itself will 
cool the motor. 

The pistons are cast in .steel, and ai-e extra 
light. The connecting rods are attached to a 
single throw of the crankshaft. The crankshaft 
is made of nickel steel and is l>alanced bv counter- 
weights, which are taking the place of the fly- 
wheel. No camshaft is used and a pinion is 
attached to the end of the crankshaft, which 
drives the timing geai-, oil pump, and ignition 
timer. 

The G. & A. carburetors have been adopted for 
the Anzani motors and an extra light model 
specially constructed for aviation is used. The 
carburetor operates entirely automatically. 




The ignition l)y (i-volt stdragc battery and higli 
tension mmltiple unit coil or liy high-tension 
Bosch magneto. 

Splash lubrication. The oil is distributed 
through all parts of tlie motor by means of a 
rotary oil pump. 

All motors are fitted with a thrust bearing, 
which is placed outside of the crankcase. in case 
a pushing force is required, and inside of the 
crankcase when a pulling force is needed. 

.Vfter the success obtained with the 3-cylinder 
motor Anzani decided to construct also 4 "and 5- 
cylinder motors. The 5-cylinder motor has proved 
quite a success. This motor is furnished either 
in 50 or 100 h.p. The same principles of con- 
struction of the 3-cylinder motor have been fol- 
lowed for the 5-cylinder. The cylinders are equally 
distributed over the circumference. Special at- 
tention has been given to the lubrication system 
and the oil is forced by means of a pump through 
a system of piping to all the bearings of engine. 

Anzani is one of the pioneers in the manufac- 
ture of aviation engines, and Bleriofs success in 
crossing the English channel with an Anzani en- 
gine established an enviable reputation for this 
engine. 

Among the famous aviators which have used 
the Anzani engine we can mention the following: 
l>leriot, Iielagrange. Morave. Molon, Olieslaegers, 
Leblanc. Masnet, de Lesseps and Balsan. 

The following machines have been from time 
In time "Ansani installed:" Bleriot, Hanriot, 
lellifr, A'endome, Xieuport and Dulujnnet.

EVERY dav there are visitors to tlie PER- 
MANENT EXPOSITION, wanting to 
see this motor or that, tires, mag- 
netos, propellers, et cetera. 

The scheme has not been a complete suc- 
cess, by reason of tlie very fact that some 
advertisers are too successful in getting or- 
ders beyond tlie immediate supply. Not a 
single motor has yet been shown in the exhi- 
1)1 1 ion room. 

Witliin the last week tliere have been added 
several most interesting exhil)its, among them 
a propeller of the American Propeller Co., the 
Pennsylvania tire exhibit, a sainple board of 
Roebling wire and cable, H. M. H. Mills cloth, 
Rubel Co. wood, Goodyear fabric. Vacuum Oil 
Co., etc. ■ 

The value of tlie exhibition to all is at once 
apparent, and every manufacturer is earnestly 
asked to send in sample products just as soon 
as it is at all possible. 

Manufacturers should send a supply of their

A SIMPLE AA^AY TO DRAAV A PARABOLIC CURVE 



To construct a parabola (iu a simple manner) 
draw the line AB ; and AC perpendicular 
to it. On AB lay otf the points, equi- 
distant. P. G, D, etc.. as many or as few 
as desired, and- at any arbitrary distance. Draw 
from these points the perpendiculars FP, (lE, DI. 
etc. With P as a center lay off the arcs GP, DK. 
HI. etc. Bisect AF at V. Taiie any point O 
between V and F. erect perpendicular OL and with 



given point F; and all points on curve must be 
equidistant from these two. Hence, all radii must 
be taken from F. FE =: AG, FJ = AH, etc. 

To duplicate a particular rib from printed 
data (if same is a parabola), where the greatest 
depth of curve and the length of the chord is 
given, one may follow this method : 

If the greatest depth (or the depth at a cer- 
tain distance bacii) is known to be. say, 4%

F as center and OA as radius cut OL at L. 
AG = PL. Then VLPE, etc., are points on 
curve. Draw a "fair" line through the points 
L, P. E. I, etc., and you have your curve. The 
chord VR may be drawn ))etween any points, 
dependent upon the depth of curvature and place 
of greatest depth desired. Other methods may be 
found in text-books. The degree of curvature 
depends on the arbitrary distance AF. and this 
distance must be selected to give the desired 
curvature. 

A parabola is defined as a curve, any point 
of which is equidistant from a given line and 
a given point. The given line is AC and the 



in., and the chord is 4V3 ft. (54 in. divided by 
4% in. z= 1 in Hi), lay out a trial parabola, 
as shown in sketch, using some arbitrary distance, 
say, 3.0 in., for AF. When complete take a 
straight-edge 4*4 ft. long and move along the 
parabola until a T-square laid on the straight- 
edge will show the necessary depth at the required 
point. If incorrect redraw, using another distance 
for AF. 

To draw a parabola to a scale of 1 in. to the 
foot, with the gi-eatest height 41/2 in. at 18 iu. 
back, give AF a value of 3/10 in. This can be 
drawn on cardboard and then cut out with scis- 
sors and used thereafter in making drawings by 
working around.

IIELICOI'XER PATENT FOR SALIO. 

W. E. Colyer, Box 391, Saranac Lako. N. Y., 
has a patent to dispose of. No. .S97.T."i8. Sept. 1, 
llidS. Tlie macliiue covered therein is of the heli- 
copter type, comprising- two superposed screws or 
discs on concentric iipriglit sliafts driven by bevel 
gears, and rotating in opiiosite directions. There 
is a framework upon whicli is mounted tlie engine, 
driver's seat, etc.. witli means for sliifting tlie cen- 
ter of gravity b.v a lever in order to tilt the lift- 
ing screws and give the whole apjiaratus a forward 
movement. Steering right and left is effected by a 
vertical rudder at the rear of the frame. 

There are two claims in the patent, as follows : 
_ \. X flying machine comprising a main frame, 
'oppositelr rotating • jiroiiellrrs carried thereby, a 
"snpplemi'nlal frani'^ suspended from the main frame, 
said siiiiplemental frame comprising hangers pivot- 
ally connected with the main frame, a bottom bar 
pivotally connected with the hangers, and a link 
joining the hangers above the bottom bar, drivi> 
gearing supported by the main and supplemental 
frames for driving the propellers, and adjusting 
means connected with the bottom bar and link of 
the supplemental frame for shifting the portions of 
said frame to change the center of gravity of the 
machine.

A NEW PEINCIPLE FOR AUTOMATIC STAIilLITY. 

To the Editor. — Stability under all conditions 
is a n(H-essity to a successful aeroplane, and an 
automatic form of maintaining the e(|uilibrium has 
an incalculable advantage over one that retiuires 
the constant attention of a skilled operator. A 
pendulum arrangement of the weight is cumber- 
some and awkward, as is also the gyroscope, and 
a complex superstructure is always at a great dis- 
advantage. Neither do I believe that any perman- 
ently rigid type of supporting surface, even such 
as i'.ell's tetrahedronal cell system, can success- 
fully meet all conditions. 

I set out to lind some arrangement of the sup- 
porting surfaces simple in construction that would 
(•(lualize the jiressurc^ throughout the machine in 
.ill atmosiiheric disturbances. I wanted something 
-inch that as one side of the machiiu' would be 



tilti'd up under sudden luiexen pressure, the pres- 
sure would be equalized and equilibrium restored. 
I wanted the angle of incidence to alter itself to 
meet changing conditions, and I finally worked out 
the following method : 

I'lanes are hinged to each side of a central frame 
or chassis so that the lines of connection (B B 
in figures) will diverge sharply to the rear, giving 
the vertical projection of tlu' central frame the 
form of a triangle with base to the front. At 
points near the extremities of the ojiposing planes 
a cable is fastened which runs through a i)ullev 
(A in Fig. 21 located below the level of the planes. 

Now you will note that swinging one of these 
planes down will increase its angle of incidence, 
and, as the two sides are joined by the cable, a 
movement on either side causes an opposing move- 
ment on the opposite side. As the cable runs 
freely on the pulley, extra pressure exerted on 
one side as by a gust of wind will force that 
side up, but while doing so would decrease its 
angle of incidence (to the possible extent of form- 
ing a negative angle), lessening the pressure due 
to the advance of the machine, and not only would 
that alone tend to preserve equilibrium, but the 
cable would exert a downward pull on the opposite 
plane, tending to increase its angle of incidence, 
consequently equalizing the pressure. 

An additional effect may be secured if we raise 
the pulley ; then both planes will be raised and 
their angle of incidence would be dtx-reased. while 
lowering the pulley would have the opposite effect, 
thus transferring to the nuiin supi)orting planes 
the function of extra elevator planes. 

Still further is it to be noticed that if the pulley 
be held in place by a properly adjusted spring so 
that changes in pressure due to the relative speed 
of the machine would raise or lower the pulley 
(hanging the angle of incidence to meet the 
changes. 

Bracing and trussing would have to depart from 
])resent methods, as the entire strain is concen- 
trated on the cable and hinge connection, but after 
considerable experiment I believe that a machine 
of this type may be built lighter, siiupler and safer 
than a so-called rigid type. At least that has been 
my experience with gliders. The principle may be 
applied to either monoplanes or biplanes, though 
several inherent features of the biplane seem to 
favor its use with that type. Financial circum- 
stances have i)revented me from experimenting in 
reference to the elimination of the rear auxiliary 
planes, except in the case of gliders, but I think it 
can be done with advantage in a power driven 
machine. 

Note. — The principle is protected by patent right 
ill this country.

CORRECTION. 

To the Editor. — I beg to call your attention to 
the error in the specifications of drawings on pages 
105-106 of September Aeronautics. On page 106. 
paragraph 4, lines 19, 20 and 21 ("The longitudinal 
action front and roar is simultaneous. There is no 
transverse action of rear rudders except for emer- 
gencies. The advantages") sliould be in para- 
graph 1, page 100, lines number 5, 6 :md 7. 

In paragraph 5. page 105. line 0, you have "(Fig. 
II) B. E. are adjustable," etc., which should be 
(Fig. II B), etc. 

Any one who is interested enough to make this 
correction will get a great deal more sense out of 
the three paragraphs. A number have evidently 
figured this out for themselves, as I liave re- 
ceived several inquiries and will probably receive 
more. — Very truly yours.

Ladis Lewkowicz, who will be remembered in 
connection with the importation of a Bleriot ma- 
chine into this country, has been able to m<U^e a 
flight of 40 miles in length in Holland. 



James Montgomery's play. "The Aviator," was 
presented by Cohan & Harris in Boston, opening 
September 5. There were two boxes full of avi- 
ators, including Grahame-White, Brookins, Ralph 
.Tohnstone, and others. The comedy is cleverly 
written and very funny. 

The "Bleriot XI," which was built by the Church 
Aeroplane Company, made a big "hit" with the 
audience, as they were surprised to see a real 
live machine, which takes five men to hold when 
the engine is started up. 



The Aeronautical Society of Great Britain is 
going to present Octave Channte with its gold 
medal. The ceremony has been delayed by his 
recent sevei'e illness, but he is expected to be ovei' 
in England in the autumn. The medal will prob- 
ably be presented at a public dinner. 



The list of aviation pilots of the .Vero Club of 
France now totals 207.

MOISSANT FINALLY REACHES LONDON. ^^ •'^ V 

London, Sept. 6. — J(?Iin' B. Moissant, the .Vmeri- 
can aviator who started from Paris on August 
16 for a flight to London in his Bleriot, and who 
after crossing the English Channel with his 
mechanician as a passenger, met with several mis- 
haps, finally reached the Crystal Palace at 5 :30 
o'clock this afternoon. After circling the palace 
he flew off in the direction of Beckenham without 
alighting. 

Moissant. with his miechanician, Albert Fileux. 
as a passenger, left Paris Aug. 16, and reached 
.Vmiens without mishap the same evening. The 
next day he left .Vmiens and crossed the Channel 
with a passenger, thereby making a new record. 
He was compelled to descend at Tilmanstone, 
about seventy miles from London, because of high 
winds. He resumed his .iourney to London the 
next day, but was compelled to land at Upchurch, 
about 'thirty-five miles from London, on account 
of the wrecking of his propeller and damage to 
his planes. 

He started again, on August 20, but met with 
another accident after going about five miles and 
landing at a place between Gillingham and Twy- 
dale. He made other attempts to reach London 
since that time, but was compelled to descend after 
.making very little progress. 

Moissant started again this morning, but had 
to come down at Oxford, some twenty-five miles 
from London. lie made slight repairs here and 
then started on the flight which brought him to 
his goal early this evening. 

NE'VV RECORD FOR HEIGHT. 

Issy, Sept. 8. — George Chavez, a young Peruvian 
aviator, broke the world's record for height, rising 
in a 50 h. p. Bleriot monoplane S»%il2 ft. in 
a flight taking 41 minutes. 

DESTRUCTION OP ZEPPELIN VI. 

Baden Baden. Germany, Sept. 14. — The Zeppelin 
VI., took fire after au oxijlosion, while being- 
warped into her shed. 

The Zeppelin VI. during the past eighteen days 
has made thirty-four passenger trips, covering 
about 2, Goo miles, and carrying more than 3(mi 
passengers. The flights of the dirigible were made 
regularly, often in unfavorable weather. The air- 
ship ascended at 11 :20 o'clock today with twelve 
passengers for a trip to Heilbronn. It had covered 
abmii twenty miles, when a motor in the forward 
gondola acied badly. It was impossible to effect 
satisfactory repairs, and after some time had been 
spent in the futile effort, the airship returneii k 

here. <!, ^^ 

The Zepjielin VI. will be best remembered by 
its notable flight from Friedrichshafen to Berlin^j. 
when it carried Count Zeppelin, the inventor, on a - 
visit to lOmix'ror William. The airship was l)uilt 
in 1909, but had since been altered and enlarged. 
Suspended from the center was a luxuriously fur- ■ 
nished cabin. She carried a crew of ten men. '," '-^

American Sportsmanship. 

FOR the sake of Amerieau sportsmanshiii, ii 
must be ui-god that, in defending- trophies 
gained by Americans, apparatus of home manu- 
facture be employed. 

It is with sincere regret that one remembers it 
seemed desirable by some of our representatives 
to use foreign made balloons in the four past 
Gordon P.ennett balloon races. 

The ItlOB Gordon Bennett was won for America 
in a foreign made balloon, the only entry. In 
190i7, at St. Louis, but one of our three balloons 
was of American make. At Berlin, in 1908. two 
of the three American balloons were made in 
Europe. In 1909 we had but one representative. 
Mix, who is looked upon in France as a French 
man, and he used a French built aerostat. 

It should be made a rule that defenders oi 
American sports use apparatus of home make. Is 
it not a hollow victory to win from France an 
American cup in a Frenda balloon V 

Will the plaudits of dB' American people be 
very hearty if American sportsmen see tit to use 
a foreign balloon or a foreign aeroplane in the 
two international events to be held here this FallV 



IT is sincerely hoped that our representatives 
in the aviation race will be picked after elim- 
ination trials. When, in 1907, Aeuonautics 
urged elimination trials for the 190'8 Gordon 
Bennett balloon race one of the officials of the 
Aero Club of America raised holy protest at the 
bare suggestion of such a socialistic scheme. The 
idea! With satisfaction Aeuox.\utics views the 
elimination race at Indianapolis. 



Dr. II. W. Waldeu, a plucky would-be aviator, 
who recently had a rather narrow escape from 
serious injury in his first attempt at flight with a 
new monoplane, tells of an amusin;; incident rela- 
tive to the accident. 

After having his broken collarbone and three ribs 
bandaged by the local hospital surgeons, he pro- 
ceeded to the railway station to take the train 
for Kew York. While waiting on the platform 
he noticed a man walking nervously up and down 
and finally the object of his concern addressed 
him. 

"Are you not Dr. Waldeu V said he. 

"Yes." 

"Well, I thought you were dciid ! I'm llic uii 
dertaker of the town." 



Personal. 
S. E. Iiinquent, Esq.. 

Dear Sir: — There evidently is a well- 
founclecl impression amongr the aeronaii- 
tically inclined in this country that I am 
putolishing- AERONAUTICS for the ben- 
efit of my health ; or else tliey imag^ine 
the mag-azine is some wonclerf ally pro- 
ductive g-old mine. 

I freely admit that the financial health 
of the paper has improved considerahly 
within the past year, and it migrht be 
now considered convalescent. I don't 
like to think of the possibility of a re- 
lapse. 

Other publications of an aeronautical 
nature have come and g^one or have 
leaning's in the latter direction. They 
never "come back" — to stay. But AERO- 
NAUTICS has always managfed to pull 
through any sinking- spells, thanks to 
the hearty support of its ever-increasing- 
readers, who have appreciated what I 
have been trying to accomplish. 

Now, please don't think that your con- 
tinued support is not desired — for it is. 
UNDRESSED TACTS. 

There is quite a number of unpaid re- 
newals on the records. The delinquents 
have had several requests to come 
across, but they have NOT responded, 
either one way or the other — not even 
when there -was inclosed an addressed 
postal with the official portrait of Uncle 
Sam. in the corner. 

If I can't get attention for my letters, 
there is only one thing left to do — and 
I have done it herewith. If anything is 
read through, it's AERONAUTICS. I 
knovz you want the magazine for you 
be"-an when it -wasn't quite so g-ood as 
it is now. I know many of you person- 
ally, and I am certain you do not mean 
to let yoitr subscription cancel by de- 
fault. 

"DO IT NOW." 

Very truly yours.

THRILLING NIGHT BALLOON TRIP 

By Dr. Thomas E. Eldridge. 



THE voyage from Phihidelphia to Daubuiy, 
N. II., Aug. 3 and 4. was a brilliant success. 
and suriJassed any other fiif;ht I have ever 
undertaken. The peculiar feature of this 
trip was that it was made chiefly in total dark- 
ness, a rare experience, that has "peculiar charms 
such as are impossible to describe. Mr. Welsh 
Strawbridge and myself ascended from I'oint 
Breeze at 9 :28 on Wednesday night, rising imme- 
diately to an altitude of about 1,000 ft., at which 
lieight we passed in a north-northeasterly direc- 
tion over the city. As we left the city, we passed 
into total darkness — darkness so deep that we 
could not determine what were the particular 
points over which we were passing. Indeed, so far 
as locality was concerned, it was possible only to 
distinguish the general character of the country. 

At 12 :35 we passed over a number of moun- 
tains, which we realized through our drag rope 
catching. At 1 :10 a. m. we passed over another 
river, and at that point we found ourselves buried 
in the deepest and most ojipressive darkness. 

SAJLINf; OVER THE .MOUNTAINS. 

.^^11 through the night we passed over moun 
tains, lakes, towns and rivers 

All this time we were enveloped in such darkness 
as is impossible for me to describe. I can only 
say that as we were passing through it, I thought 
of the first chaptei' of the Book of Genesis, of the 
chaos that existed before the world began and of 
the terrible immensity of space. It was a darkness 
overwhelming, and both Mr. Strawbridge and I 
were glad when we saw the tirst signs of day- 
break. That was about 4 :10 a. m. Over the great 
chains of mountains we could see the inky black- 
ness gradually fading into gray. 

SAW WONDERFUL .SUNRISE. 

And such a color effect as we saw in the transi- 
tion of the black through ihe various shades of 
gray is something that cannot be described ; to be 
appreciated it must be seen. And when the day- 
light disclosed to us the world below, we agreed 



that never before had we seen such wild, rugged 
scenery as that lying at our feet. Finally we saw 
the sun, a great globe of red fire, climbing over 
the mountains and shedding his light upon a beau- 
tifully cultivated region over which the balloon was 
passing. At .j :1() we went over another river, 
and then we beheld all the beauties of sunrise, all 
the gorgeous tints and shades of red and yellow 
and blue. 

All during the trip we had not suffered from 
erild, l)ut about 7 o'clock Thursday morning we 
were obliged to put on a little extra clothing. At 
that tim(> we passed through a hailstorm, the 
particles of which were about the size of sago 
kernels. That was at an altitude of 1.3,750 ft. 
About 8 o'clock we rose to a height of 15,100 ft., 
about which time, we afterward learned, we had 
passed over the Rugged Mountains and the Kear- 
sarge Mountains, the highest points in New Hamp- 
shire. At that time, too, there was a thunder 
storm going on beneath us, and we could see the 
lightning flash and hear the thunder. After that 
we saw wonderful cloud effects. 

All around us as far as we could see were im- 
mense towers of clouds, thousands of feet high, 
forming a gigantic basin, in the middle of which 
floated the balloon. These clouds gradually ap- 
proached us from every side until we were entirely 
enveloped in them. So dense, indeed, were they 
that we could not see the balloon's bag above us. 
At the same time the clouds caused the gas in 
the balloon to condense and we then knew that it 
was time for us to descend. 

From an altitude of 15.100 ft. we dropped into 
the midst of woods two and a half miles north of 
Danbury, Merrimac county. N. H. As we descended 
the balloon was caught between four trees and we 
were obliged to climb down to the ground. Mr. 
Maxfield, the proprietor of the farm, greeted us, 
and at once, with his men, proceeded to chop down 
the trees so that the balloon might be disen- 
tangled.

or over. 

*Point P.reeze. Pa., \\\%. 16. — Dr. Tlios. Edwin 
Eldridge, pilot, Dr. (Jeorge 11. Simmerman and Ira 
L. Brown in the "Phila. II" to Negro Mt.. Md.. 
2l'2.37 miles. The piuty left at 8:27 p. ni. and 
rose above the clouds in the moonlight. The log 
says: "A most wonderful elfeet. The dull, sombre 
shades of gray conlrasled markedly from the light, 
airy effect by day. I'assed over Ilanovoi' and Get- 
ty.s"burg at 2 "a. m'. .Vt :! a. mi. crossed the Allegheny 
mountains. The sight was wild and picturesque 
at daybreak, whrn the sun lifted the balloon to 
14,000 ft. The landing was at 'J :05 a. m." Dr. 
Eldridge now holds the Philadelphia record for 
altitude, distance and duration. 

Hamilton. ().. .\ug. IS. — Mr. and Mrs. George 
R. Howard, Mrs. Charles Trontman and Mr. and 
Mrs. Albert IIolz in the "Drifter" to Dry Ridge,

Topeka Club Buys Honeywell Balloon. 

St. Louis. Mo., Aug. 28. — H. E. Honewell piloted 
Messrs. Emerson, Cole and Sweet of the .\ero 
Club of Topeka on a demonstration trip. After 
making three landings, the last being near Jersey- 
ville. 111., the party hurried back to St. Louis with 
the balloon. The Topeka men bought the bal- 
loon for the use of the members of the club. 
It has a capacity of 40,000 cu. ft. In addition 
to the four people, 16 bags of ballast were car- 
ried and Ijesides that, two landings along the 
way were miade. At the inal descent, there were 
10 'bags still left. 

Mr. Honeywell is using his balloon "Centennial" 
in the Indianapolis race, and other entrants have 
Honeywell-built balloons. A new dirigible balloon 
has been completed by him along original lines 
which will soon be given a try-out. The gas (en- 
velope is flat on the under side. There is a large 
rudder for controlling the lateral movement o* 
the balloon attached to the stern, while on the 
bow there is fixed a larger plane for horizontal 
steering. The machine is provided with an alumi- 
num propeller and has a capacity of 0,000' cubic 
feet of gas. 

The French-.Vmerican Balloon Company, of which 
Mr. Honeywell is director, has done a surprising 
business in the manufacture of balloons. The 
gas balloons have gained and hold many records. 

Indianapolis, Ind., Sept. 3. — Capt. G. L. Bum- 
baugh. Ray Harroun and F. L. Galnaw to Millers- 
ville, Ind. 

Pt. Breeze, Philadelphia, Sept. 3. — A. T. Ather- 
holt, pilot, H. H. Knerr and Clarence P. Wynne 
in the "Penn. I." to Pipersville, Pa., a distance 
of 33 miles. The ascent was made in a driving 
rain. The balloon was allowed to go up to 0,000 
feet without being able to get out of the clouds 
into clear sky. No land could be seen and even 
the statoscope failed to work and cigarette papers 
were used in its place. 

.lackson, Mich., Sept. 3. — J. H. Wade, Jr.. and 
X. Leo Stevens in the new Wade balloon "Buck- 
eye." 

Indianapolis Speedway. Sept. 5. — G. L. Bum- 
baugh. Dr. L. V.. Custer and Dr. C. W. Mills in 
the "Indiana." had an exciting experience in an 
ascent at the dose of the auto races. .\ storm 
came up .iust after getting up and the rain came 
down in sheets. Vyi and down the wind took the 
balloon and the aeronauts did not dare use the 
little ballast they took along. The drag rop.» 
caught electric light wires on descending and 
broke them. The final landing was in the tree- 
tops. The trip lasted about 25 miautes. 



CLUB NEWS 



The Aero Club of Pennsylvania has had 

delivered a new 35,000-foi)t Stevens balloon, called 
the "Pennsylvania I." A "Balloon Section" has 
been formed, to the treasury of which a limited 
number of members pay .$2.50 weekly for ten 
weeks. Each week lots are drawn and three mem- 
bers have the privilege of an ascent. See "Ascen- 
sions" for records. 

A series of flight exhibitions will be held at the 
club aviation grounds at Clementon, N. .7., the 
first being on Septemlier 24-25, when Charles F. 
Willard will make his second appearance before 
Philadelphians. It is possible that Graham-White 
and Harmon will fly the following week. 

The Aeronautical Society, at an extra- 
ordinarily well attended meeting on September 8th, 
was favored with an interesting and valuable talk 
on autogenous welding, by Mr. A. Davis, of the 
Davis-Bournonville Co. A complete apparatus was 
used for demonstrating. Holes were cut in thick 
steel, steel tubes welded together and plates of 
steel cut quickly in two by the 2,300 degree flame 
of an oxy-acetelin blowpipe. 

On August 25th was held a discussion on "New 
Devices," Wilbur R. Kimball described his new 
model. G. L. Lawrence told of his experiences in 
aeronautics, beginning with tlie hot-air balloon. 
With his exi)erience as an actor to augment his 
effervescent humor, his tale was well worth hear- 
ing. 

The Aero Club of lions' Island has been 
incorporated witli the Secretary of State to carry 
on experiments in aerodynamics and to advance 
the science and sport of aviation. The directors 
for the first year are : Howard C. Brown and 
Charles Wald, of Brooklyn : Francis C. Willson, of 
Flusliing ; Henry I. Newell. Jr., of Richmond 
Hill, and John II. Lisle, of Glen Cove.

BALDWIN'S VULCANIZED PROOF MATERIAL 

USED IN THE U. S. GOVERNMENT DIRIGIBLE AND SPHERICAL BALLOONS 

WILL last from five to six times as lon^' as a varnished balloon. The weight is always 
the same, as it does not require further treatment. Heat and cold have no effeet 
on it, and ascensions can be made as well at zero weather as in the summer time. 
The chemical action of oxygen has not the same detrimental effect on it as it has on a 
varnished material. Silk "(louble-walled VULCANIZED PROOF MATERL\L has ten 
times the strength of varnished material. A man can take care of his PROOF balloon, as 
it re(juires little or no care, and is NOT subject to spontaneous combustion. Breaking 
strain 100 lbs. per inch width. Very elastic. Any weight, width or color. Will not 
crack. Wati-i-proof. No talcum powder. No revarnishing. The coming balloon material, 
and which, through its sujicrior qualities, and being an absolute gas holder, is bound to 
take the place of varnished material. The man that wants to have the up-to-date balloon 
must use VULCANIZED PROOF :MATERIAL. Specified by the V. S. SIGNAL CORPS.

Vacuum Oil Company, 29 Broadway, New York City. June 6, 1910. 

Dear Sirs: — I am pleased to report the success we have met with in 

the use of MOBILOIL in lubricating- the engines in our aeroplanes, and 

to say that it maintained its reputation in my Albany-Xew York flight. 

Very tridy yours, 

GLENN H. CURTISS. 



Vacuum Oil Company. 29 Broadway, New York City. June 14, 1910. 
Gentlemen: — I wish to let you know that the oil which befoided 
my spark plugs was not your oil. I used MOBILOIL going to Phila- 
delphia and had no trouble. Owing to misunderstanding, I was supplied 
HAMILTON there with some other oil, which caused the trouble resulting in my 
descent. Had I used MOBILOIL on my return flight, I sliould, un- 
doubtedly, have made the trip home without a stop. 

Very truly yours, 

CHAS. K. HAMILTON. 

Famous Aviators Who Use Mobiloil: 

Baldwin, Bleriot, Brookins, Cody, Curtiss, Farman, Fournier, Frisbie, 
Hamilton, Johnstone, Latham, Paulhan, Radley, Roe, Sommer, Willard, 
Orville Wright, Wilbur Wright, Ogilvie. 

Builders of Aeroplanes and Aeroplane Engines Who Also 
Use Mobiloil: 

Antoinette Freres, Voisin Freres, Wright Brothers, 
Glenn H. Curtiss. 

Are YOU Using the Right Oil on Your Car? 

The most important thing left entirely to the judg- 
ment of the owner in the operation of his automobile 
or aeroplane is the selection of a lubricant. Is it not 
significant that aviators generally, in this country and 
Europe, use Mobiloil on their motors exclusively ? 

WARNING — To prevent substitution of inferior oils, see that cans are sealed.

The Cheapest Speed Indicator 

Price is relative. First cost means little. It's the years of satisfactory service that deter- 
mines real value. Here the Warner Auto-Meter stands supreme— without a rival. It is so 
refined in construction that it remains absolutely accurate, dependable and reliable for years 
under conditions which would ruin a $250 chronometer in 
an instant. Auto-Meters over 8 years old are as accurate- 
to-the-hair as when new. We never yet have seen a 
"worn-out" Auto-Meter. Other speed indicators become 
inaccurate in a short time, and must be replaced every 
year or 18 months, yet they cost almost as much at first as 

Warner AutO-Mcter 

Quality has so much to do with satisfaction and the pleasure that 
goes with it that even the owner of a moderate priced car should 
afford a Warner Auto-Meter. It's good business judgment to 
use it.

cyl ER ON AU T I C S AND 

By Lieut.-Col. W. A. Glassford. 



WAR 



su;nal corps, u. s. army. 



PHILOSOPHICALLY, it would no doubt 
be interesting to trace tbe order of 
thought on the subject of man's flying 
hat obtained from remote antiquity down to 
he time of the invention of the hot air bal- 
lon in 1782, but it would not be of any use 
1 a technical sense. The only advantage that 
light be derived from such an inquiry would 
e a better understanding of the feeling which 
ctuates the public mind on this subject to- 
ay. The general notions that prevailed down 
3 the time of the discovery of the barometer 
nd of the air pump were not of a scientific 
rder, and their study would mainly lead to a 
ontemplation of the superstitions that have 
Jtarded the development not only of aero- 
autics but of man. 

The Egyptians, 4.000 years ago, possessed 
le necessary skill for making a hot air bal- 
)on with its equipments — cordage, basket and 
II, and so doubtless did Chinamen, and many 
ther peoples who then inhabited the earth. 
: seems very certain, however, that it never 
ccurred to any of them to try their skill 
1 this direction. The Egyptians believed that 
len flew at times, but when they did they first 
irned into birds ; they certainly never believed 
lat man would ever be able to rise in the 
ir, unaided by occult or supernatural power. 
Lud this is true of all peoples down to the 
jventeenth century. 

Man, down to a recent epoch, was not in the 
ossession of the necessary facts or natural 
rinciples to enable him to think on the sub- 
let intelligently ; furthermore, the kind of 
otions he cherished was frankly hostile to 
^'ery thought that might lead to the discovery 
f principles useful in the development of aerial 
avigation. He peopled the air with gods, 
ngels. spirits, jinns. devils and witches and a 
ost of other imaginary beings, and gave to 
lem the absolute rule of it. The atmosphere 
?ing, in his imagination, the special realm of 
le deities and of the evil spirits, might not be 

cspassed upon. 

Allusions to man's flying are not wanting in 
le stories and legends of antiquity ; but they 
e generally in some way connected with 
ystic or supernatural notions. Nowhere do 
e find the simple belief that a man unaided by 
pernatural power would ever be able to rise 
the air. Among the legendary flying ma- 
lines none occupies a more conspicuous place 
an the flying horse. Originating in India, its 
rformances are recorded in th^ §tpri^s of 



Egypt and of Greece, of Persia and of Arabia; 
its career ending in the memorable ride of Don 
Quixote. We have, also, accounts of flying 
chairs and of flying carpets, and of other 
things, all capable of carrying passengers, when 
moved by magic power or by enchantment. 
During the middle ages many men, also, were 
supposed to have acquired the art of flying 
through their knowledge of magic and necro 
mancy. 

Such were the ideas that prevailed on the 
subject of aerial navigation down to the dis- 
covery of the barometer in 1645. The few sug- 
gestions that are met with previous to this 
epoch, which do not fall into the category 
above mentioned, are so devoid of detail in 
their description as to make their considera- 
tion useless. Speculation concerning aeronautics 
gave rise to no tangible ideas on the subject 
down to the discoveries which led to the con- 
struction of the barometer and of the air pump, 
and the further discoveries which followed 
experiments with these instruments. The dis- 
covery of the barometer marks the dawn of 
knowledge that led to the development of aero- 
nautics. Aeronautics has sprung from a purely 
scientific order of thought, and its develop- 
ment has depended in all its stages upon the 
progress of science and the consequent develop- 
ment of the modern industries. 

The barometer brought to light properties 
of the atmosphere that are of prime importance 
in aeronautics, but they were of a nature so 
contrary to the then accepted notions that 
they gave rise to endless discussions as to the 
truth of the new discoveries. Nevertheless 
from this time on we meet with suggestions 
in which some of the. true elements of the 
problem are taken into consideration. A knowl- 
edge of the facts that the atmosphere has 
weight and that its density diminishes as the 
altitude increases and that it is possible to 
produce a vacuum, could not fail in time to 
influence speculation on aerial navigation. 

In a comical history of a voyage to the moon, 
which appeared about this time, mention is 
made of smoke as furnishing the lifting power 
used in a flying machine. In 1670 we meet 
with a proposition to utilize a vacuum con- 
tained in large, thin, globular copper vessels, 
with a sufficient description of the apparatus 
to show that the author was totally ignorant 
of the pressure of the atmosphere and of course 
unaware of the fact that his vessels could not 
possil)ly contain a vacuum, and be light enough 
to rise in the air.

Xeaiiy a cciiiury later, in 1755, we meet with 
a proposition to collect fine diffuse air_ above 
the. highest mountains and to inclose it in a 
bag of enormous dimensions, bigger than the 
city of Avignon, and composed of the strongest 
sail cloth, with which ■ apparatus Uie_ author 
thought a whole army with its munitions of 
war might be transported at one time through 
the air. These suggestions, however absurd, 
in part, yet show the influence of a better un- 



146 



dcrstaniliug of the true nature of the atnios 
phere as revealed by the then recent discov 
eries. 

The discovery of hydrogen m 1765 brough 
into the problem of aerial navigation its mos 
important factor, a gas fourteen times lightei 
than air. Nothing now was lacking in ordei 
to produce the balloon but to inclose this g* 
in a suitable vessel. The industries .of th( 
epoch furnished all the necessary materials foi

cAERONAUTICS IN THE cylRGENTINE 



By Henry Helm Clayton. 



TIIF: Argentine Aoro Cliil), like most aero clubs, 
began with ballooning. The club was 
founded the i:!th of .Tanuary. lOdS, under 
the presidency of Engineer (ieorge Xewltery, 
who made his first ascen.sion in a free balloon 
on the 2.jth of December of the preceding year, 
accompanying Senor Anchorena in the balloon 
"Pampero" of 1.200 cubic metres capacity. The 
balloon ro.se from the ground of the Sociedad 
Spcirtiya in Palerino. and after crossing the La 
I'lata riyer, impelled by a pampero wind, descended 
in the department of Conchillas. Uruguay. 

The "Pampero" made nine ascents, during which 
there (jualifled as pilots Engineer Xewberv. Dr. 
Edward Newbery and Major Waldino Corre'a. In 
a night ascent made by Dr. Edward Newbery. ac- 
companied by Sargeant Edward Romero, this bal- 
loon was lost, and nothing has since been heard 
of the pilot, his companion or the balloon. This 
occurred on the night of Oct. 17, 1008. 

Owing to this misfortune, the memlD^rs of the 
.\ero Club dispersed, and for some time aerosta- 
tion was put aside, since all were impressed by 
this loss of a gentleman widely known socially 
ind of a useful soldier. Xeyertheless. one daV 
Engineer Horacio Anasagasti. one of the direc- 
tors of the .\rgentine Aero Club, bought the 
lalloon "El Patriota." and made an ascension 
in the 24th of .January. HIOO. accompanied liy 
Kngineer Oeorge Xewbery as pilot. 

Following other successful ascensions, the presi- 
Jent of the Club undertook to reorganize the 
issociation. and hi.s patient efforts were rewarded 
vith comiplete succe.ss. since the reorganized clult 
las a full membership amounting to 200 members. 

Slowly but steadily the Club grew stronger, pos- 
;essing at present a park for aerostation, a club 
louse, and four balloons, with all accessories. The 
•lub house contains a room for the secretary, a 
:itchen. living rooms for the attendants, toilets. 
.nd an ample aerodrome, where concourses of 
yiation are held periodically. 

The balloons "Edward Xewbery." "Buenos Aires." 
•Patriota." and Iluracan." of 2.20(1. l.G<M). 1.200 



and sill* cubic meters, respectively, are in use 
every Sunday and holiday, when the weather con- 
ditions are favorable, for pleasure ascensions and 
for distance or point-to-point racing, etc. 

Among the ascensions notable for the distance 
run. the hour at which it was made, and the 
fact that it has crossed foreign countries, may 
be mentioned that completed by the president of 
the Club. Engineer (ieorge Newbery. who in the 
balloon "Iluracan" began a voyage at 11 p. m. 
on December 2."). 100!). from' the grounds of the 
gas company. Kio do la I'lata, situated in P.el- 
grand, and impelled by a strong pampero wind, 
crossed the river La I'lata into the Kepublic of 
Uruguay, crossed centrally over the entire length 
of that country and descended in Bagi. in the 
state of Rio Orand'e do Sud. Brazil, luiving run 
a straight line distance of 550 kilometers in 1."! 
hours. 

An aviation meeting was held in April. 1010. 
under the au.spices of the Club. At this meet there 
were entered several of the well-known French 
machines, as the Bleriot and Farman. and th'e 
meeting proved a great succss. The president of 
the Club made the necessary flights to secure a 
pilot's license. Other meml)ers of the Club have 
in contemplation taking out a pilot's license, and 
it is possible that in a short time this will be- 
come a very important part of the ('lul)'s activity. 
But at pres-ent ballooning continues to be tlie 
most important sjyort. and in the point-to-point 
racing, which occurs very fre(iuently. the four 
balloons l)elonging to the Clul) arc usually seen 
in the air at once.

few miles from the harbor in the mouth of the 
La Plata. A short distaace to the eastward 
lies the ocean. Fortunately the prevailing winds 
are from the northeast and the members of the 
Club have found by experience that they can 
(ioat inland on this surface wind and then rise 
into a contrary or eastward moving current 
and return almost to their landing point. These 
two opposing currents are made much use of 
in the point-to-poiut races. In a recent contest 
of this kind some of the pilots went far out to 
sea in the upper current, and then sinking into 
the lower, returned to the land. But feats of 
this kind, and the nearness of the sea for other 
reasons, always subjects the pilots to more or 
less danger, and one of them has fallen into tlie 
sea so many times that he is called the "aquatic" 
pilot. 

The Aero Club has rooms in the building with 
the .Vutomobile Club, where they hold business 
and social meetings, and entertain their friends. 
This building is a fine house with ample rooms 



for entertainments ; a good library, including a 
library of aeronautics and a splendid cuisine. Many 
of the members of the Aero Club are enthusiastic 
automobilists, and are now greatly interested in 
the art of aviation. 

Owing to the fact that he was a member of 
the Aero Club of Now England and a pilot in the 
.\ero Club of America, the writer was made an 
honorary member of the Argentine Aero Club, and 
was royally entertained by the president, Engineer 
Newbery, and liad the pleasure of meeting most 
of the prominent members, including St. H. Ana- 
sagasti and (i. G. Davis, chief of the Argentine 
Weather Service. The members of the Aero Club 
make much use of the reports of the weather 
service in- planning their voyages, and fre(iuently 
carry insduments with them belonging to the 
service for nhtaining records in the upper air. 
The obsciN ;ii ions made by the pilots in regard 
to the directions of the air currents at different 
heights are adding much to the knowledge of 
the air movements in the Southern Hemisphere. 



cylEROPLANES FLYING IN MEXICO 



By E. L. Ramsey. 

The new airship now being constructed in San 
Antonio for the Marquis de Casanova of Mexico 
City, met with an accident in the building shedi, 
according to a letter received by the Marquis, 
and its completion will probably be delayed for 
three or four weeks, as it will be necessary to 
send to France for duplicates of the parts in- 
jured in the mishap. 

Tlie Marquis expects to go to the Texas city 
to bring back the new flyer sometime within the 
next morith, and immediately thereafter will make 
tliglits about the city. 

Among the many new devices attached to the 
machine will be a rudder of novel design partly 
built from the plans of the Marquis, who has had 
considerable experience with aerial craft in 
France. The entire control of rudder, planes 
and engine will be from the steering wheel. The 
engine being situated immediately back of the 
drlTer's seat, and all parts within easy reach 
of the aviator. 



Miguel Lebrija, the aeronaut who made an 
ascension last Sunday morning, descended about 
6 o'clock that same evening at a place about 
three kilometers from Cuatitlau on the line of 
the National Railway of Mexico, having covered 
during the six and a half hours he was in the 
air a little over fifty kilometers. 

Lebrija said that he obtained a height of about 
1,000 meters above the height of the Valley of 
Mexico, wliich would make his height above sea 
level about 10,500 feet. He is enthusiastic over 
the trip and claims that with his larger balloon 
he will establish a record for twenty-four hours. 

Captain Nicholas Martinez of the Mexican Ai-my. 
and who is one of the attendants of General 
Bernardo Reyes, who at present is making a tour 
of France, made a very successful flight in an 
aeroplane, accompanied by a captain of the Spanish 
Army, Sr. Samaniego, and by the Spanish aviator, 
Laygori. 



WHO W^ILL WIN THE GORDON BENNETT? 



The newspaper man ran across a pessimist the 
other diay who seemed in great distress. The P. 
unburdened himself to the N. M. in this fashion : 

"Do you realize," said he, "that the prospect 
for American supremacy in the Gordon Bennett 
aviation race, at least, is apparently very poor? 
Now, in other events during the Belmont Park 
meet we have a chance for duration and height 
records with machines already making tlight». 
There is no question that a Wright machine will 
stay in the air as long and go as high as any 
other machine which may be brought into competi- 
tion. It might be said, without any suggestion 
of a 'knock' that none of the Curtiss aviators have 
shown thus far form enough to warrant beating 
on duration and height performances, comparable 
with existing records. And none of the Wright 
machines at present known to the public can vie 
with the latest foreign speed record, although the 
Wright company is reported as building a special 
fast machine. Curtiss' fastest speed yet made 
with his machine figures 52.58 m. p. h., at the 
Boston meet." 

"How about the amateurs" 'I asked the N. M. 

"Clifford B. Harmon seems to be the only ama- 
teur in this country who has done much flying, and 
that has been done with a foreign machine. He 
certainly stands no chance in a speed contest, 
such as the Gordon Bennett is. Ills two-hour 
(light entitles him to consideration in duration 
flights." 

"How about Hamilton?" 



"I'll admit," said the pessimistic one, "that 
there you have something. Hamilton may find his 
110 h". p. Christie motor of sufficient power to 
bring him into the lists as a possibility." 

"It is now quite certain that Curtiss is build- 
ing a special machine and motor capable of great 
speed," vouchsafed the N. M. 

"Yes, but it is not at all certain that he will 
even fly it at Belmont Park. He has been invite<i 
to defend the cup with two others to be selected 
but has not yet given an answer to the club. The 
Aero Club of America, it is said on good authority, 
has offered to provide a 'retainer' fee, but it was 
not prepared to state the amount. 

"If Curtiss should find his new machine to be 
faster than the record made by any other aviator 
in the meet, he may challenge the Belmont Park 
fastest flyer to a speed duel. Such a race, undoubt- 
edly, would result in bringing a tremendous crowd 
to whatever spot Curtiss and his opponent might 
select for the scene of the conflict." 

Here the P. O. brought out a table of figures he 
had been working on and offered them in evidence. 

"The speed record of the world," he said, 
now 66.18 m. p. h., made in a Bleriot machine 
with a 100 h. p. Gnome engine, by Morane. The 
fastest American speed records are : 

"52. .".S m. p. h., Curtiss. Boston, 1910. 

"47.4:! m. p. h., O. Wright, Washington, 1900. 

Here the N. M. excused himself and sought morr 
congenial company.

NOTES ON FRAMING OF AEROPLANES 



ADAl'TED FItO.M AX AltTICI.E 



By O. Ursinus, C. E. 



IX I'SELESS Jlyiug mafhine constructions, or 
other, some little item will be found which 
ma.v be turned to good account by the ex- 
perienced liand. Wood is used principally thus 
far in building aeroplanes, though very recently 
some structures l)oth in America and abroad have 
been built of steel tubing. The advantage of 
wood is its light weight, great strength and easy- 
working qualities. 

Lately some efforts have been made to improve 
on solid wood construction, by using wooden tubes, 
for instance. In Boston a hollow spar (Pig. 7) 
is being made and imt on the market. 



A man l)y the name of Wolf, in (Jei-many, has 
invented a process for making wooden tubes of 
various cross-sections. This wood tubing consists 
of veneers 5 mmi. thick, glued together. This 
method was described recently in Flu(/sport, an es- 
teemed (Jerman contemporary. The grain of the 
veneer (A) runs in the direction of the axis; B^s 
diagonally laid linen. C, D, E and F are veneers 
with counter-crossing grain. These constructions 
possess enormous firmness, as the following table 
will show :

The Wolf patented tubes may be made in any 
cross-section. Planes or whole bodies can be made 
from these veneers. 

Steel tubing of various shapes has also been 



produced, as shown in Figs. ] to (!. Figs, '.i auJ 
4 are used for constructing ribs. Fig. 5 is used 
for body work, and may be used double or treble, 
as shown in Fig. 6. 



Aeronautics in the Far East. 

James W. Price, of California, who is travel- 
ing with a balloon, airship, hot air balloon, 
parachutes, etc., in the Far East, reports that 
the art is still in a somewhat backward state, 
in Tlong Kong he made a balloon ascension 
in the presence of 15,000 people. From there 
he went to Medan in Sumatra, where he in- 
tended to make an ascent with his airship at 
the invitation of the "so-called" Medan Aero 



Club, but the club could not get together the 
necessary 4,000 guilders (about $1,600) to pav 
for the inflation. Sulphuric acid cost 6c. a 
pound and iron tilings 3c.. which is of interest 
to our own airship people. So the Medan Aero 
Club had to be contented with a hot air as- 
cension. Subsequently he made a hot air trip 
for H. H. the Sultan of Lang Kat. From 
here his route lay through Penang, S. S., the 
Federated Malay States, Singapore and Java, 
where airship trips will be made.

THE ETEVE AUTOMATIC STABILIZER

A NUMBER of investigations iu the attempt 
to attaiu automatic ionsitudiiial stabiliza- 
^ tioiL ia aeroplaiw^s liave been made up to 
tlie present time, imt one has Ijeen carried 
out on a machine in full Hij;ht. A public experi- 
ment made in this direction consisted of trials 
made at the military aviation grounds at Satory. 
near Versailles. France, under the direction of 
Captain Eteve. of the Sapper-Balloonist l)attalion, 
the aeroplane used lieins a Wright, wit h the addi - 
tion of ajitoQ iatic stabilizers aftfii" the^gT'sij^n s Of 
FBt^'TiTprain. const ructcd in The workshops iTfrhe 
Military Aeronautical Laboratory at Chalons- 
Meudon. 

The first arraagement tried out at Satory waa 
composed of two planes. A and B, miorable on their 
axis EE. The axis EE is carried; by a frame- 
work G, 3.5 meters in length, attached to the rear 
transverse members of the aeroplane surfaces. A 
horizontal vane D, movable on an axis F is con- 
nected to the planes AB by rods A'./ and Kh. The 
axis of the vane is firmly fixed to a tube H. con- 
trolled bv a rod Ml through a bell-crank MHF, 



those resulting from I he manoeuvre made by the 
pilot of the aeroplane : moreover, the vane has the 
advantage over the aviator of acting simultaneously 
with the cause that produces the disturbance of 
equilibrium. In a word, the Eteve stabilizer op- 
poses all variations of the angle of attack of the 
aeroplane as would be the case if a very long, 
light and instantaneouslv-acting empemnage were 
fitted. 

Under certain circTmistances, it is necessary 
to be able to vary the miagnitude of the angle 
of attack of the aeroplane, as when the inclination 
of the trajectory is to be modified, for example. 
To preserve the automatic action of the stabilizer, 
prior to, during and after the manoeuvre effected 
by the pilot, the axis P of the vane can be raised" 
or lowered by the aid of a lever under the control 
of the aviator. All displacement of F involves a 
change of (Miuilibrium of the vane and conse- 
quently a modification of the angle of attack of 
the planes .IB (Fig. 3, d and e). This indirect 
control of the stabilizer offers the great advantage

When the lever is fixed, axis F is immovable 
and the stabilizer vane struck by the wind, moves 
sensibly in the belt or layer of wind immobilizing 
the planes AB, which arc ci>mi)('nsated ; the angle 
of attack of these planes is. then, invariable when 
the direction of the air current is constant. But 
when this latter varies, the movement of the vane 
is modified and the planes .IB turn in a direction 
contrary to that of the vane. 

In the "rearing" (cabnif/<'\ of an apparatus fitted 
with the stabilizer, the vane I> is tilted and causes 
the planes AB, to turn in a direction contrary to 
their proper movoment. This tends to correct or 
straighten out the aeroplane : when it plunges, the 
reverse effect is ])roducc(l and the manwuvre is 
executed without iuterfrrcnce, owing to the sim- 
plicity of the mechanism, a (|uality indispensable 
to an automatic stabilizer. 

The planes AB, considered as depression rudders, 
automatically partake of tJi<; fiame movernents as

sion rudder and stabilizer at the same time.

THE PRESSEY AUTOMATIC CONTROL 



A SYSTEM for aiUomatically maiutaiuing the 
i'(|uilibriiim of au aeroplane has been pat- 
eiiti'il by Dr. B. J. Pressey, of Newport 
News, Va., in several foreign countries, and 
patents are pending in othei-s as well as in the 
United States. 

In, the patent drawings reproduced herewith Ihe 
device has been fitted lo a biplane using aili'rons 
for lateral, and horizontal rudders for longitudinal. 
stability. The system is designed to be adapted 
to any type of aeroplane. 

The aeroplane is ecjuipped with a manually oper- 
. ated, vertical rudder, o. at the stern, and a hori- 
zontal, manually operated, front control. 4. in front. 
At the ends of the main plane, and about midway 
between the upper and lower sections thereof, there 
are supplemental planes, 5. 

In connection with these supplemental planes 5, 
there is emplo.ved a gravity influenced weight, the 
aviator in his seat, for holding them in a hori- 
zontal, or substantially horizontal, position when 
the main plane is traveling on an even keel : and 
for causing them to tip when the main plane 
dips laterally, to port or starboard, the planes 
.") having a lifting effect upon the depressed 



supported from the main plane ; and the other 
arms of the port and starboard bell-crank levers 
1(>, are connected by rod 17, which has an eye 
18, for receiving the segmental rod 19, secured 
to and pro.iecting from cross bar on seat sup- 
porting yoke 7. When therefore, the main plane 
tii)s downwardly on the starboard sid«', the rod 
17 will be moved bodily to starboard, and the 
starboard balancing plane 5. will be inclined so 
as to raise its forward edge and de|)ress its rear 
edge, while, at the same time, tlie port balancing 
plane 5, will be inclined so as to depress its 
forward edge, and raise its rear edge, thereby 
causing the starboard balancing plane to exert 
a lifting effect, and the port balancing plane 
to exert a depressing effect upon the main plane, 
with the result of restorhig the main plane to 
an even keel, at which time the lialancing planes, 5, 
will have resumed their normal, horizontal posi- 
tion. 

When the main plane dips downwardly on the 
port side, a reverse action takes place, with the 
like result of restoring the main plane to an 
even keel. In order to correct fonvard and aft 
dip of the main plane, fore and aft balancing 




end of the main plane, and a depressing effect 
upon the lifted end of the main plane, so as to 
correct such lateral dip of the main plane, and 
restore it to an oven keel. 

The aviator's seat. 6. is carried bv voke 7. 
suspended from a fore and aft shaft, 8, the lat- 
ter Iteing pivotally mounted in bearings at ends 
of bar y which is secured to a transveree shaft. 
10. pivotally mounted at its ends in suitable 
bearings attached to the main plane 1, thus pro- 
viding a gimbal .ioint, whi«h permits free tip- 
ping movement of the main plane in any direc- 
tion, in respect to said seat; the licai.. having ^ 
-Uormal teudencytojiang^^ reason 

of rhe^-^fferfT)! }?favTfation iipon the" weight. 
represented by the seat and its occupant. Lateral 
tipping of the main plane is caused, to effect 
corrective movement of the lialancing planes 5, 
in the following manner : lOach of the balancing 
planes 5, is pivotally supi)orted, somewhat for- 
ward of the centre by bearings 11 located in 
bracketed arms 1U. which arms are rigidly con- 
nected with uprights, which connect the ' upper 
.md lower sections of the unain plane. 

To the forward, upper ecige of planes 5, con- 
nection is made by means of rod ].">, fo one 
arm of a bell-crank lever, 14, Ihe latter being 
pivotally mounted upon a fore .tnd aft pin 15, 



planes, L'O and S-', are provided. These planes 
are carried by transverse rock shafts, which may 
be pivotally mounted in any suitable way. upon 
structures carried by main plane. In tlie pres- 
ent instance, the forward balancing plane is 
pivotally mounted in extensions 21 of the frame 
22 which carries the forward, manually operated, 
horizontal ascending and descending plane 4. 

The aft balancing plane 2."! is jiivotally monnied 
in extensions 24 from frame 2.") which carries 
the vertical steering plane ?>. Pro.iecting uiiward 
from' bar 9 is an arm 2(>. which is connected liy 
rod 27 to an arm 28 pre.iecting uj)wardl.\- froiii 
forwai-d balancing jilane 2tl and by rod 29 to an 
arm ."(). projecting downwardly froin aft balancing 
plane 2;;. 

When, therefore, there is a downward tij) of 
the forward part of the main plane, retention 
of its vertical ijosilioii liy the armi 2(> will cause 
the forward lialancing plane, 20 lo tip so as to 
raise its forward edge and depress its after 
edge; while at the same time the after balancing 
plane, 2.'!, will tip so as lo depress its forward 
edge and raise its after edge, with the result 
that there will be a lifting etl'eet on the fore 
part of the main plane, and a depressing elTect 
on Ihe after part of the main i)Iane. which will 
restore said main jilane to an even keel. A

reverse action takes place when the after part of 
main plane has a tendency to dip. In case the 
aeroplane departs from an even keel, and dips 
tor instance, forwardly and to one side, all four 
balancing planes would immediatelv be brought 
into action. 

In ascending and descending, however, depar- 
tures from the normal inclinations of the main 
plane are necessary and in order that the for- 
ward and aft balancing planes 20 and 2.3 shall 
not interfere with voluntary descent or ascent 
the aviator's seat should, in making such ascent 
or d'f^scent. virtually be locked to the main plane 
so far as allowing forward and aft motion of seat 
To secure this result, there is employed what 
may be term/ed a sliding-bar 31, firmly secured 
to lower section of main plane and parallel to 
the lateral swing of the aviator's seat. To the 
ordiiiai-y foot rest 32. connected with the aviator's 
seat, a supplementary foot rest 33, is hinged and 
I his supplenicutary foot rest carries an extension 
whicli ends in a lug 34, which lug normally 
swings .nist above and free of the sliding-bar 31 
being held in this po.sition by a light spring 3.5. 

In case the aviator wishes to ascend, he places 
Iii.^ foot upon the supplementary foot rest; tie 
weight of the foot overcomi\s the force of the 
spring and allows the lug to be carried down and 
in trout of the sliding bar. thus rendering neutral 
for the time being the forward and aft balancing 
planes. During such time, the forward and aft 
lialancc would be under the operator's control bv 
means of the manually operated plane 4. In case 
of voluntary descent the lug 34 is dropped be- 
hind l)ar 31. until such voluntary descent is ended

It IS absolutely necessary, in making a turn

"kY '.,*,! ^^^ ™'''*° plane shall be inclined or 
banked, to a degree proportional to the radius 
S-i , ^.^"■^''' '^"•fl to the speed of the aeroplane. 
Each difterent curve, at the same speed, demands 
a different inclination, as is also demanded bv 
each variation in speed in rounding like curves- 
,^. If.f """"fi^^T /I expected to give the desired 
lesult with absolute certainty. 

• \K ^u^ aviator desires to make a turn to the 
right, he would first manipulate the vertical rud- 
der .j. by means of lever 30. The aeroplane would 
begin to make the turn. 

At this instant, centrifugal force would come 
into action and cause the aviator, in his seat to 
swing outwardly to an extent .iust in proportion 
to the radius of the curve, and the speed of the 
aeroplane. The outward .swing of the aviator's 
seat causes the port balancing plane .5. to be 
so inclined as to present its under surface to 
the air pressure, whereas th(> upper surface of 
the starboard plane is presented. This would im- 
mediately cause an inclination of the main plane 
to the degree where said main plane would be 
at right angles to the susiiended weight the 
aviator in his seat, thus allowing this .special 
curve, at this particular speed, to be negotiated 
with satety. 

If it is desired to make a curve of less radius 
or at a greater sp(>ed, c(^ntrifngal force, acting 
upon the suspended aviator's seat, will cause 
It to swing out to a corivspcndlngly greater ex- 
tent, thereby causing the main plane to be banked 
to a greater degree. 



LETTER TO AERO CLUB MEMBERS 



TIIK following letter was received iust liefore 
going to press. .Ieroxautics will gladly de- 
vote such space in subsequent issues ns'may 
be required for letters of suggestion or aid 
lu co-ojierating with other members for a better- 
nient of conditions in the Club, and for the making 
of It a more serviceable institution. — The Editor. 

New York, Oct. 15, 1910. 
To the Members of The Aero Club of America : 

The article which appeared in to-day's papers 
stating the view expressed by Mr. Moi.'^sant. who 
ileclares thiat this country is far behind France 
in .\eronautics. is so eminently well founded upon 
fact that it naturally causes one interested in the 
iidvaneenient of the art in this country to pau.se 
md think. It appears that hundreds of aeroplanes 
liave been made and sold as well as hundreds of 
)ilots' licenses issued in Prance. Can it be that 
there are so many of those things which have 
been done which should hiave been left undone 
ind so many of those things which have been left 
iiidone which should have been done in the short 
listory of American aeronautics that we are at 
list forced to the realization of our own short- 
•omings by the advanced condition of aeronautical 
iffairs in France? 

Concerted effort is naturally dependent for suc- 
cess upon proper organization. The real head of 
ie art, the Federation Aeronautique Internationale. 
s recognized in France through the Aero Club of 
''ranee, and is recog-nized in the United States 
hrough the Aero Club of .\merica. This seems 
o put it up to the Aero Club of America to ex- 
ilain why they cannot accomplish as much with 
American genius and capital as has been aecom- 
ilished with Frenchmen under the same system of 
peration. In the solution of the problem" the fol- 
Dwing questions arise : 

Can it be that the form of government of the 
lero Club of .\merica is too autocratic to be 
ompatible with the democratic gpjrit of our 
imerican institutions? 



Why is it that the Aero Club of America never 
holds regular meetings for enabling its members 
to get better ac<juainted and to co-operate? 

Is tlw^ International Aviation Meet to be held 
at Belmont Park under the auspices of the Aero 
Club of America ; and if so. why is it the mem 
bers have not been enlisted or consulted? 

Why does the Aero Club of America not own 
and control its property directly instead of through 
the Aero Corporation, which is governed by the 
same five men who originally owned and con- 
trolled all the property of the Club to the ex- 
clusion of the members? 

Why did the Aero Club of America assume the 
responsibility of entering into such an important 
contract as that which was made with the Wright 
Company considering that it might have seriously 
checked progress in the art of aviation, without 
first consulting the members? 

Why has a democratic National Organizatir)n of 
Clubs not been encouraged? 

Why have the members not been invited to take 
part in Club affairs? 

I take this means of reaching the members of 
the Aero Club of .\merica as there seems to be 
no other way of bringing these vital points before 
them. Yours respectfully, 

Louis R. Ad.vms. 



Dr. Luzern Custer, of Dayton. O., has presented 
Leo Stevens with one of his new design statosco])es. 
which Dr. Custer described and illustrated in a 
recent issue of Aerox.m'tics. The article of Dr. 
Custer was translated and printed later in one 
of the German aero magazines. Stevens used this 
on the first occasion and pronounced it the finest 
instrument of its kind yet invented. Clifford B. 
Harmon also tried it and with great success.

THE MISSING LINK IN AERONAUTICS 



By John D. Pursell. 



PUBLICATIONS which, a short time ago, 
searched tlie dictionary for conservative 
words, when they touclied on aeronautics, 
now give t'tiH jjiay to their iinasinations, 
and seldom fail to worlc in something lil^e this: 
"We have the aeroplane now only In its infancy. 
One may be sure that improvements will be made 
in. the macliine such as are not now dreamed 
of," etc., etc. However, they never commit the 
indiscretion of naming any iioneral lines along 
which this miraculous development will take 
place. The modest pun)ose of this article is to 
point out precisely that opportunity for develop- 
ment. The facts will speak for themselves. 

It seems almost incredible, but it is, neverthe- 
less, true that some very homely and everyday 
law.s of Mother Nature have been studiously ig- 
nored by the elect, like the ugly duckling, because 
things have prospered very well, so far. without 
them. I refer to Inertia, that property of all 
ponderable bodies (including air) ; and' its ac- 
companying factor, Accelerating Velocity. These 
two potent influences are destined to play a very 
important part in the devel(i])mi'nt of all aerd- 
cars^ — helicoptere and flapping wing devices, as 
well as the aeroplane. Consideration for your 
patience coustrains me to limit my comments 
to the aeroplane, alone. 

Does the present aeroplane exhibit that grace- 
ful impression of reserve strength that stands 
forth so strongly when a touring car purrs lazily 
over a small hill? Verily, I trow not. Rather 
let us think of a seven passenger car, equipped 
with a bicycle motor, nearly stalled on. the car 
tracks in front of a rapidly moving street car. 
Where is the exhibition of magnificent reserve 
power for emergencies? I submit that the mental 
attitude of tire driver in either case is very similar. 
They both must win out by virtue of personal 
skill alone. 

Suppose for a moment that the 50-horsepower 
Curtiss biplane requirt>d but one horsepower in 
level flight. Wouldn't this solve all the essential 
problems of safety, reliability and commercial use- 
fulness simply because of the tremendous, fifty- 
nine hundred per cent, reserve power absolutely 
under the operator's tinger? The mastery of 
adverse elements would be unutterably simplifled. 
This is not an idle supposition. It is advanced 
merely to illustrate graphically the truly marvel- 
ous advance which will accrue from any con- 
siderable economy in horsepower consumption over 
the present figures. 

The most elBcient aeroplane of to-day carries 
about 50 pounds for every horsepower actually 
delivered at the propeller. A 25-pound bird, how- 
ever, instead of expending half a horsepower, 
exerts scarcely a tithe of that energy. Let us 
investigate this discrepancy. 

Motors have reached practical perfection, as far 
as small weight per horsepower is concerned. 
Lighter motors cannot l)e expected to exhibit 
the reliability so vital to the successful aeroplane. 
Instead of crowding the motors, let us look 
rather to the sustaining planes and see why 
they are so ineflicient when compared with their 
prototypes in nature. 

In the standard plane of to-day, the approximate 
angle of incidence is about 6 degrees. At 6 
degrees, the drift or head resistance developed 
during flight (exclusive of framing, etc.) is 
about one-tenth of the total weight carried. To 
l>e exact, for every 206 pounds lifted, there are 
21.7 pounds of drift, which, multiplied by speed 
of the machine, and figuring an allowance for 
loss in transmission, etc., represents the horse- 
power required to carry the 20G pounds. It is 
perfectly clear that if we can design a sustainer 
capable of producing the necessai-y lift, with 
speed and wing area remaining the same, at only 
a fraction of 6 degrees angle of attack, we will 
need only a fraction of the horsepower now re- 
quired to carry the weight with planes set at 
G degrees. 



Such a sustainer i,s described below : 

In the first place, the vitally important faolor, 
tliat which every flying creature employs to sus- 
tain itself, rarefaction over wings, body and tall, 
is almost totally disregarded in the present de- 
sign. (This does not appear quite consistent in 
view of the general acceptance of th(> fact that 
there is rarefaction over the tops of aerojilane sur- 
faces. — Editor.) A study of the transverse ver- 
tical section of a bird's wing will show that de- 
fective pressure must exist during flight, over a 
large portion of its upper surface, after a certain 
forward velocity is attained. The wing moves 
edgewise through the air, and the air passes par- 
allel with the under wing surface. The air stream 
divides at the thick front edge of the wing, and the 
portion of the air stream represented by the thick- 
ness of the wing, is deflected upward and over 
the upper surface by the wing's curved forwai-d 
section, the extreme foi-ward edge of which is 
nearly on the same plane as the under surface 
of the wing. This air thrown upward by the 
wing's curved edge, cannot reverse instantly and 
maintain close contact with the upper surface 
of the wing, on account of its inertia. The air 
pressuri', therefore, drops below atmospheric, be- 
tween the passing current of air and the wing's 
upper surface, the space between lieing filled by 
eddies at a pressure below that existing in the 
free air (to be found underneath the wing) 
the degree of rarefaction depending on the speed 
and the degree of their inclination to each other. 
This, of course, somewhat resembles the "slip" 
of a propeller. 

How slight the degree of rarefaction required 
for flight is at once apparent when we remem- 
ber that we require only two to four pounds 
lift per square foot, whereas an absolute vacuum, 
were it possible to obtain it, would yield about 
one ton to every square foot of surface. 

A satisfactory demonstration of the importance 
of defective pressure may be obtained by taking 
an ordinary l)ox kite and removing the vertical 
planes, thus allowing the outer air to be drawn 
into the rarirtcation forming over the lower planes. 
The loss in lifting power of the kite will be ap- 
parent. On the other hand, by extending the 
vertical keels a slight distance at)ove the upper 
horizontal planes, thus protecting the rariflcation 
forming over the upper planes, from any side 
currents, the increase in lifting power of the 
kite will be noticeable. 

In the face of the above, we must agree that 
proper conservation of the rartficatiou above a 
sustainer is essential to economv of energv in 
flight. 

Now we come to a factor in the proposition, 
which seems to, have been ignored heretofore, 
viz : The efticiericy of a sustainer varies Inversely 
as the fore-and-aft dimension. 

Referring to diagram : The dotted curve 2 :! 
represents the line of equal rarefaction, produced 
by the air stream in flowing over the wing 4. The 
space 5 indicates the useful rarefaction, which 
corresponds somewhat to the "slip" of a propel- 
ler. This line 2 ,">, must represent an increas- 
ing downward velocity, because air possesses weight, 
and conseciuently, inertia. This is self-evident. 
As this is an accelerating downward velocity, the 
distance 6 7 must be only one-sixteenth of the 
distance 8 9 because it is one-fourth as far 
back from the front edge of the wing. If the 
accelerating velocity factor is admitted (and it 
cannot well be denied) the distances 6 7 and 
8 9 must compare as the squares of their dis- 
tance back from the front wing edge. 

The expansive power of air affects the rate 
of acceleration, but it has nothing to do with 
the ratio, and it is the ratio with which we are 
dealing. 

The distance 8 9. being sixteen times as great 
as the distance 7. the average angle of lil$i- 
dence for the large wing is four times that .^^e-

liuired by a quadruplann, consisting of four planes 
nipasui-ing the same as 2 7, superimposed. Tliough 
thi' distance 8 9 is sixteen times the distance 
7, the radius of its arc 2 8 is, of course, four 
times the radius 2 6, hence the degree of incidence 
is not sixteen times as great, but only four times. 

Inasmuch as the efficient angle of incidence 
for the (juadruplane is only one-fourth the angle 
re(iuired by the monoplane, it will lift an equal 
weight, at same speed, but requires only one- 
fourth as much horsepower as the large mono- 
plane. 

Keference to the diagram will show that an 
octoplano would yield eight times the efficiency — 
retjuiring but one-eighth the horsepower to pcr- 
from the work, etc., etc. 

Therefore : Efficiency of fi sustainer varies 
inversely as the fore-and-aft diniension. 



sustainers will require but one horsepower for 
every twelve in the present machines^ — quite a 
saving, we must admit. The 206 pounds men- 
tioned above, would be levitated with oniy 1.8 
pounds head resistance, instead of the 21.7 pounds 
required with the larger plane. And this, too, 
with no increase in wing area or speed. This 
m«ans we can figure about 600 pounds carrying 
capacity to each horsepower — which open.s" uii 
vast possibilities in. the commercial machine. 

As an angle of incidence equal to but one- 
twelfth of the original 6 degrees — namely, om-- 
half degree — would prove impractical with the 
present form of aerocurve, we substitute the 
natural design found in a bird's wing. The flat 
lower side is to pass parallel with the lowei- 
air stream ; the thick forward edge divides the 
I wo air currents, and the sloping upper surface 




Or : The angle of incidence varies directly 
as the fore-and-aft dimiension of a sustainer. 

Also : A numlK'r of corollaries, but they are 
so obvious that I will not take space to set 
them forth. One would deal with Prof. Langley's 
paradox ( V) of economical high speeds. That 
is, a plane driveiL at quadruple speed requires 
only one-fotirth the angle of incidence (we see 
why from above diagram), therefore developing 
four times the speed at no additional expense in 
horsepower. 

In' other words, there is an intrinsic advantage 
derived from the narrow planes — and no apparent 
disadvantages — even constructional, for stronger 
machines may be built by reason of their cellular 
compactness. 

Constructional limitations will discourage the 
use of planes much under 6 inches deep. Com- 
pared with the present 6 foot deep planes, these 



corresponds to the angle of incidence, yielding 
the lift, through rarifaction and minus pressure. 
And it is this minus pressure that does the work, 
anyway. This thick wing cannot be taken: aback at 
the front edge, when held at small angles, like 
the present aerocurve would be. 

A multiplane possesses intrinsic fore-and-aft 
stability. By designing the "vertical" bracing like 
the sustainers, and arranging them at dihedral 
angles, we may practically eliminate idle head 
resistance in the wings, and the lateral stability 
will also be automatically increased. 

With moderate application of the proposition : 
"Efficiency varies inversely as the fore-and-aft wing 
dimension," and its corollaries ; together with 
proper conservation of the rarificafion above a wing, 
we usher in the era of true flight. The comi- 
mercial flying-machine is now a probability. Ex- 
celsior !

BelmontInternationalMeet. 




As we go to press the aiTaugements are about 
completed for what promises to be the most 
extraordinary meeting yet held in America. 
The "International Aviation Tournament" at 
Belmont Park, Long Island, New York, from Oct. 
22 to 30, inclusive, offers total cash prizes amount- 
ing to $67,300, to be competed for under the rules 
and regulations of the Federation Aeronautique 
Internationale. 

The Gordon Benjiett race, perhaps, is the prin- 
cipal feature of the meet and is the primary cause 
of its being held. A year ago, Aug. 28, G. H. 
Curtiss won the cup at Rheims, France, making the 
fastest time for 20 kilometres, 15 minutes 50 3/5 
seconds, a speed of 47.06 m. p. h. 

In the 1910 Gordon Bennett cup race, Oct. 29, 
.$5,000 cash goes to the winning aviator (and the 
silver trophy to the club of the country represented 
by him) making the fastest time for 100 kilo- 
m)eti-es (62.1 miles) flown over a course of 5 kilo- 
metres (3.1 miles).

and we had intended to have a picture of Curtiss on his flight from 
Albany to New York when he used an EL ARCO RADIATOR with perfect % 
results, and another picture of J. J. Frisbie with the first twin EL ARCO * 
RADIATOR installation, and a well-worded advertisement asserting in ^ 
terse, crisp sentences that the EL ARCO was the lightest, strongest, most '^ 
efficient radiator ever devised and that the sharp cutting edges of the tubes # 
and the compactness of the radiator minimized the obstruction to the air, ^ 
and that therefore there was no other radiator so well adapted to cooling ^ 
aeroplane engines as ours. 

We had intended to claim that we were the first in this country to 
sho^A^ a radiator especially made for aeroplane work with special metal 5 
throughout and individual caps and fittings, and to remark that E. R. Hewitt, ^ 
a member of this firm, the w^ell-known designer of engines, who has been |J 
experimenting scientifically with the problem of engine cooling for years, % 
laid out the formulae which we adopted for determining the sizes of EL U 
ARCO RADIATORS for aeroplane engines. J 

In fact, we proposed to blow a very loud blast indeed on our own * 
trumpet, and impress on your mind the facts that Baldwin, Beach, Curtiss, * 
Frisbie, Gill, Dr. Greene, Russell and Wilcox, to name a few of the well- ^ 
known men, all use the EL ARCO RADIATORS, and the Boulevard S 
Engine Co., Elbridge Engine Co., Emerson Engine Co., Rinek Aero Mfg. Co. ?J 
are some of the engine builders who have adopted the EL ARCO as part 
of their standard equipment. 

All over now — You won't read this — No hope of your remembering 
that the EL ARCO RADIATOR is absolutely what it is represented to be 
as regards weight, efficiency and workmanship ; that its guarantee is abso- 
lute and that our services in any problem of radiation are entirely at your 
disposal — And all because we were too busy keeping our promises to 
attend to our own interests. Just look out next time !

Trial flights of the Latham 100 h. p. Antoinette 
showed up a speed of 69,5 miles an hour. 

THE FIELD. 

On the flying field, with Its two miles of gvassy 
level, 14 gayly colored pylons trace the aerial 
course. Starting in front of the Grand Stand the 
nymg gladiators will give a near view of their 
airmanship. Each aviator has his distinctive style 
ot launching and alighting. The machines, after 
turning the last pylon, will approach the grand 
stand at a speed of a mile a minute, mcreasing this 
as they sweep past the crowds. 

A brilliant period of preliminary flving will oc- 
cupy the three or four days before 'the Tourna- 
ment. The hangars, or sheds, in which the racing 
monoplanes and biplanes \vill be housed, have been 
finished. Aviators have begun "tuning up," trying 
out motors and testing the stability of their craft, 
in the air. Three-quarters of a mile across the 
green flying flel'dl the 30 hangars and repair shops 
are lively with corps of expert mechanics, who will 
live there during the entire flying season. "These 
stables" have already become a center of interest 
for hundreds of experts on flying. 

The cross-country flights will be out and around 
captive balloons furnished by Leo Stevens. 

COST OF SEEING THE SHOW. 

A number of boxes and parking spaces are re- 
served for members of the Aero Club of America

Curtiss Machine in Gordon Bennett. 

New York, Oct. 17, 1910i. — It is now definite 
that there will be a Curtiss aeroplane in the Gor- 
don Bennett race. This will be a single surface 
machine, with a new 8-cylin.der engine, (i. H. 
Curtiss will not fly the machine himself. Curtiss 
ha« the privilege of defending the cup without 
ent(>rlng into the elimination" trials, but as he 
will not fly the machine it is indefinite whether 
the aviators who do fly it will be permitted to 
go into the race without going through the trials. 
There will be at least two other Curtiss machines 
of regular type. Willard, Mars, McCurdy and Ely 
have all been entered. 



XHIBITION FLIGHTS OVER THE COUNTRY 



^I•KI.^■(;F^•:LD. .Mass.. Sept. 17.~Louis (!. 
ickson. of Springlieldi. Mass., made several flights 

the Stnrbridge Fair on Sept. 17. in his Cur- 
's type machine. Four short flights were made 

OSS the tield of the race track. The condition 

the field was horrible, with a pond, a swamp 

1 bumpy grounds to run over. The flights were 

de with a propeller, which had a piece knocked 

of it by a wrench which dropped into it while 

motion. 

vX()XVILI>F, Tenn.. Sept. 22-28, — P. O. Parme- 
one of the new Wright aviators, flew at least 
ce every day at the Appalachian Exposition. 
)ETROIT, Sept. 19-25. — Hoxsey and Johnstone 
V their Wright iiiMi'liines everv day according 
the schedub', 

;^has. J. Stroljel had a dirigible there. Parmeleo 
3 a great success as a flier. Some of his flights 
ted .'iO minutes, and in all of them he indulged 
"roller coasting" and other stunts. 
VLLEXTOWN. Pa., Sept, 20-24,— (J. 11. Curtiss 
1 J. A. D. McCurdy were scheduled to, flv. On 
ouut of the dangerous grounds Curtiss refused 
allow McCurdy to fly. Curtiss flew over part 
the town. It was advertised that he would 
to Philadelphia. The only possible route, with- 
going over the mountains, was full of dan- 



gers and 120 luiies in length, so (he flight was 
.given up. 

OLEAN, N. Y., Sept. 22-2:]. — Chas. F. Willard 
(Curtiss) gave exhibition flights. In starting a 
tiight, a piece was i-hipped out of his propeller, 
luit bad ground made it necessary to keep going. 
The loss of blade surface ou one side rocked the 
m^achine so that every wire was loose on landing. 

TRENTON, N. J., Sept. 26-.30.— Ralph Johnstone 
flew every day in accordance with his contract, 
meeting with the greatest enthusiasm on account 
of his wonderful conti'ol. 

HELENA, Mont., Sept. 26-Oct-. 1.— J. C. Mar's 
flights at Helena were very successful. The gov- 
ernor of the state presented him with a gold 
watch and nugget fob. Helena has an altitude 
of 4,100 feet. This is the highest that a Curtiss 
machine has flown, as far as known. 

Mars essayed a flight across the Rocky Moun- 
tains for a prize ofl'ered by Ringling Bros., the 
circus men. After some hours searching parties 
found the dismantled machine near the top of 
(ho range. Fortunately, Mars escaped injury. The 
right hand plane, front wheel and propeller were 
smashed in alighting, but the machine was brought 
back. His altitude aliove sea level is reported to 
have been 7,500 feet, a new American, record.

CHICAGO. Oct. 1-9.— Curtiss. Ely, Willard. M<?- 
Curdy and Post were the flyers at an exhibition 
conducted by the Chicago Post on a profit-sharing 
basis. Willard and Curtiss both made fine flights. 
Willard made a sensational one over a part of 
the city and went to a height of 4.000 feet. lie 
slowed up his motor and swooped down over 
Jackson Park, then up again to the grounds at 
Hawthorne track. Augustus Post did here his best 
flying to date. Two days of rain prevented flying. 

ELY STARTS FOR NEW YORK GOES BUT 19 MILES 

ATTEMPT GIVEN UP ON ACCOUNT OF 
LACK OF TI.ME. 

Eugene Ely, with the new 8-cyl. machine used 
by Curtiss at Boston, left on the 9th on an 
attempt to roach New York. After going about 
13 miles at an altitude of 1,500 feet, the car- 
buretor gave trouble and a landing had to be 
m'ade at Beverly Hills. 

This was fixed, the motor started and spectators 
helped to start the machine. In. getting off the 
front wheel hit a hidden rock and smashed the 
wheel. 

The next day, the 10th. he did not get off the 
fi(^ld when the gasoline feed pipe broke and he 
landed in a brook, smashing the whole front con- 
struction. This was fixed in a hurry and he got 
going again and flew for 25 minutes. The motor 
went dead in the air and he glided down from 
a height of 2,000 feet. In landing he smashed 
the front control again, and the distance from the 
start was but 19 miles, at East Chicago. So 
much time had elapsed that it was not deemed 
advisable to try to continue. 

Miss Blanche Scott made her debut with a Cur- 
tiss machine during the week. 

The time limit of the prize offered by the New 
York Times andi the Chicago Post is up on October 
16. Present plans do not provide for keeping the 
offer open after that date. 

SEDALIA, Mo., Oct. 1-7. — .T. C. Turpln, the 
latest addition to the Wright staff of aviators 
made his first public flight at Sedalia on the 1st, 
and flew everv dav but one during the week. 

SPRINGFIELD. 111.. Oct. 1-8.— Hoxsey took the 
machine Brookins used in his Chicago-Springfield 
flights and created great enthusiasm during the 
week. On the last day he made his great flight 
to St. Louis. 



RICHMOND, Va., Oct. .3-8.— Ralph Johnstone 
filled the engagement successfully, rain preventing 
his flying on the 5th and 6th. A rather peculiar 
accident happened while flying on the 5th. The 
Mayor of Richmond, as passenger, in his enthusi- 
asm' in waving at the crowd struck the motor 
control with his arm and shut off the motor just 
as they were risslng from the ground. Johnstone 
made a successful landing but broke a few spars, 
which were repaired on the following day. 

SHRIVER HAD BAD SMASH. 

WILMINGTON. Del.. Oct. 4-7.— Tod Shriver and 
J. J. Frisbie filled this date. Frisbie made only some 
short flights. "Slim" Shriver made a magnificent 
flight on the .Sd. over part of the town, and was up 
15 minutes in a strong wind. He landed with the 
wind behind him. did not shut off the motor in 
time, he hit the ground, bounced, then landed nose 
on and the machine rolled over. He crawled 
out and the first thing he asked was. "Can you 
fix it up for to-morrow?" The doctor found a 
bone broken in his leg. 

The machine is one built by himself, and is 
called the "Shriver-Dietz" : it is of the usual 
Curtiss type, but fitted with a 30-50 Kirkhani 
motor of a weight of 288 pounds. Bosch high 
tension magneto, Livingston radiator, Shebler car- 
bureter, propeller 6 ft. 6 in. by .3% ft. pitch, which 
gives up to 340 pounds standing push at 1,360 
r. p. m. 

BIRMINGHAM, Ala., Oct. 6-12. — P. O. Parmelee. 
a Wright aviator gave an exhibition at the Ala- 
bama State Fair. The first day a flight was made 
in a drizzling rain ; the second day there was 
no attempt at flying made on account of the 
wind being high. 

KANSAS CITY. Mo.. Oct. 7-8.— Capt. T. S. 
Baldwin and William Evans flew at Elm Ridge 
Park. One of the contests was a race between 
the two machines for .$500, offered by the Kansas 
City Post. 

Evans is a new-comer who recently bought a 
biplane from Dr. Wm. Greene of Rochester. He 
sprang into prominence by his sensational flights 
at Overland Park in his first trials, with a 40 h. p. 
Elbrldge engine. His longest flight was one of| 
about 28 miles across country.

Springlield, 111., Sept. 29. — By going 86% miles 
without alighting. Walter Brookins. in his Wright 
liplane (minus front control), broke the American 
[•ecord for cross-country flying, made by Charles 
[C. Hamilton, who set the mark of 74.31 miles in 
the flight from New I'ork to Philadelphia and 
Dack. Curtiss" longest cross-country flight was 
71.25 miles, in his Albany-New I'ork trip. 

The aviator flew for the most part at an eleva- 
tion of 800 to 1,000 feet, but occasionally dropped 
lower or mounted higher to fly in better air cur- 
rents. The average win<l for the .5 hours was 9I/2 
miles an hour, bead on. 

BROOKIXS MAKES TWO XEW REC(U!I).S. 

Not only did he make more miles in one stage 
Df the trip, but the total distance flown is greater 
than either that made by Curtiss or Hamilton. 
The latter's flight to Philadelphia from New Y'ork. 
and return, totaled 140. .54 miles, and Curtiss on his 
.Vlbany-New York flight covered 142. ."> miles. 

The flight was made under the auspices of the 
Chicago Rccord-Henihl. which offered a purse of 
lflO,000. 

The start was in Washington Park, Chicago. It 
had' been arranged for Brookins to land at Oilman 
to replenish his oil and gasoline supply. Brookins 
waited at Oilman for 45 minutes before the accom- 
panying train came in. Train started from Park 
Row Station, Chicago, at 10:02. A special car was 
attached, which was held when necessary. 

An oil pump which didn't work caused a lauding 
at Mt. Pulaski. This was repaired after a few 
minutes and tlie flight restnned. In starting, one 



of the wheels was wrenched off, l)ut Brookins did 
not know it and kept on going. From here he 
left the line of the railroad and headed directlv 
for the capital of Illinois. After circling above 
the Fair Orounds at a height of 2,000 feet, he 
shut oft' the motor and glided down, the deed 
planned successfully accomplished. 

Wilbur Wright and the newspaper men followed 
the flier in a special car attached to a passenger 
train of the Illinois Central. This had to make 
its regular stops, which gave Brookins time to 
beat the train to both Oilman and Mt. Pulaski. 

For the distances Ae[:onautic.s is indebted to 
Mr. Williams Welch, Chief Draughtsman of tlic 
Office of the Chief Signal Officer, U. S. Army. 



AVIATOR HOXSEY MAKES NEW 
^^L, JRECOi 

Flew 91 Miles frorri "Springfield to St. Louis. 



ST. LOUIS, Oct. 8. -Arch Iloxsey, in a Wright 
biplane, flew from Springfield, 111., to the Country 
Club grounds at Cla\ton. St. Louis county, to-day 
and established an American sustained flight record 
in an aeroplane by rnvrrinu )j|B^'miles in an air line. 
His time fop'f t W ' H <i niiien was 2 hrs. 45 min., an 
average of -Stet m. p. h. 

His objective landing place was the aviation field 
at Kinloch Park, but because of his failing to find 
the grounds he descended eight miles away. He 
alighted on the aviation field at 3. .30 P. m'. His 
time in the air was 3 hours. 

Iloxsey tried to find the field, and circled within 
three miles of it five times. His engine could be 
heard when he was not in sight. He mistook the 
smoke of a brick plant for the tar fire on the 
field, and could not locate the Held. 

He was seen from' the aviation field at 2.1-1. 
Soon as Walter Brookins could get an aeroplam- 
started he went aloft to guide his fellow birdman 
to the field, but Iloxsey veered to the south and wa.i 
lost to view. Bombs were exi)lod(>d and the band 
played as loudly as possible, but the aviator did not 
hear the guiding noises. 

He landed at the country Club, five miles from 
the field, at 3.11. After he had learned the direc- 
tion of the aviation field he went into the air again 
and landed safely. 

The flight was the opening event of a tea days' 
meet vmder the axispices of the Aero Club of St. 
L(.uis.

TIIK Stebbins-ijcyiU't AcroplaLU' Co., of Nor- 
wich, Conn., ai(j biiildint; aeroplan-i's of the 
triplam- type, which liave a detachable mid- 
dle plane, therel)y changing from the tri- 
plane to the biplane type when desired. They 
are different from all other American aeroplanes 
now on tlie market, as they involve the use of 
three main planes^ — two coml)ination front hori- 
zontal rudders and two combination rear horizontal 
rudders. They are beautiful in apj^earance and of 
simple construction. All Joints are firmly held in 
place by castings of a special aluminum alloy, 
being strongly built and having a number of novel 
and original features, several of which are espe- 
ciaftly praiseworthy. Although this machine only 
haa a twenty-four foot spread and only twenty-six 
feet long over all, its total amount of supporting- 
area is 400 sq. ft. ; weight 6(Mj pounds in flying 
order, and have a lifting capacity of approximately 
TOO pounds more. 

Fnnnc. — iCntirely of a selected grade of Oregon 
Si)i-uce, tinishi'd down to a smooth surface and 
varnished. All struts are fish shape and set in 
alumiinum sockets which are bolted to top and 
lower l)eams with special strong bolts of small 
diameter. The middle i)lane is set inside of the 
six upi'ights and held in place liy aluminum cast- 
ings. A flexible twisted 7-strand wire cable and 
Stebbins-tiejTiet turnl)uckles are used for trussing. 

Planes. — -Top plane is three sections, laced to- 
gether, having a 24 ft. spread and 7 ft. depth : 
midd'le plane in two sections, each of 7% ft. in 
length by ft. deep, and set 5 ft. apart for 
engine ; bottom plan<' in one piece, 16 ft. long, 
and a depth of ."> ft. : a total supporting area 
of O.50 sq. ft. These i)lanes are set ;5i/^ ft. apart 
and are set at angles of degrees and so ar- 
ranged as to have the greater amount of lifting- 
area above and the greatest weight below the ceii 
t(,'r of gravity. The miiddle jiJane is detachable, 
thereby changing from the Iriphuii' to biplane 
type when desired. 

lUiiintriiclion. — Itilis are huiiiunted of two pi(>ces 
of spruce finished down to '-j .\ % in. cross sec- 
tion dimensions with true curvature of about 1 in 



-U: and fastened to the beams by a special alutni 
num casting. No. 2 Naiad aeroplane covering h 
used in covering the plane and pockets are sewei 
in for the ribs. 

Rudders. — Two combination elevating rudders an 
set well up in front, each containing 18 sq. ft 
of supporting area and arranged to work in 
unison, independently, or in opposite directions 
In Model "B" machine are also two rear small 
elevating rudders which work in unison with the 
front rudders. One vertical rudd<^r of H} sq. ft. 
is suspended rear of a small stationary horizontal 
plane in Model "A,"" while a small vertical rudder 
of only 6 sq. ft. is hung Ixmeath the small station 
ary plane in Model "B." The elevating rudders 
are so arranged as to balance the machine while 
in flight. Wing tips are also used in balancing. 
Uiidd<^r beams are held in place by a special two- 
piece casting which forms a hinge, thereby making 
a quick detachable joint. 

Mounihuj. — The Curtiss type chassis is used for 
mounting with three \Yeaver 20-in. wheels and 
Hartford '•Aviator'' tires. Rear wheel gauge is 
(JO inches and 15 ft. wheel base. In Model "\'>" 
a .spring skid is arranged below the main skid 
in such a way as to automatically dro]) when' 
aeroplane leaves the ground and absorbs all sliock 
when landing. 

Poicer riant. — Model "A" is fitted wiih Caiiirron 
25-oO h. p. four cylinder air cooled motor with 
a :^'^-m. bore and o^-in. stroke, witli Itoscli 
high tension magneto and Uinek Aero (."o. pro- 
pel'lor, giving very good results. A Model "C" 
Holmes rotary 7-cylinder motor, which is similar 
in design to the famous Gnome Motor, is being 
installed in Model "11." This motor has a 4x4

DE LESSEPS CROSSING THE CHANNEL IN 
HIS BLERIOT 



Does not the graceful, 
sure, and steady flight of 
the monoplanes inspire you 
with confidence and a de- 
sire to fly yourself in one 
of these machines ? 

Since Bleriot flew the 
English channel over 400 
people have taken up the 
use of his machine. It 
holds the records for speed, 
endurance, and high flying ; 
its greatest performance 
being the flight of George 
Chavez across the Alps. 
Moissant flew^ from Paris to 
London w^ith a passenger, 
after having made but three 
flights previously in one of 
these machines. 

The Beach Monoplane 

is of the Bleriot No. 11 
(cross-channel type). It is 
fitted with a powerful gyro- 
scope w^hich prevents side- 
tipping and gives it far 
greater automatic stability 
than is obtained with any 
other aeroplane. As a result 
you can fly in high winds 
without danger of upset- 
ting and without fatigue 
from maintaining your 
equilibrium in the usual 
way by hand. 

We can supply the 
Beach Monoplane in two 
types and sizes. The prices 
of these are $5,000 and 
$7,500 respectively.

flight. Glenn H. Curtiss won the 
trophy in 1908 and 1009, and unless 
his Albany-to-New York flight is 
surpassed during 1910, he will be- 
come its permanent owner.

with side movement or slight turn. The rear 
vertical rudder is operated with a foot control. 
I'lisiine control levers are conveniently placed 
wiihin reach of the left hand and foot lirake on 
the front wheel. An arrangement is to be tried 
out. whereby the front wheel will be connected 
witli the steering device in much the same man- 
ner, as a bicycle is steered on the ground. 

Hugh Willoughby's First Flights. 

Hugh L. Willoughby has made his first flights 
with the "War Hawk," at Atlantic City Beach. 
The flights were under 100- yards and less than 
lOi ft. altitude, but the machine got in the air 
at a speed of only 20 miles an hour, running 
over a track made of smooth boards about 150 
ft. in length. Mr. Willoughby found the steer- 
ing easy and natural, and a little drop of the 
starboard wing was corrected with a Curtiss shoul- 
der control. The patented control of the engine, 
with right foot pedal, described in Aeronautics 
last year, worked to perfection. 

The front and rear horizontal rudders worked 
in conjunction with each other as in the Parman 
machine and some of the Wright aeroplanes. The 
lauding wheels are arranged similar to the Far- 
mau. The total weight of the "War Hawk" is 
1.111!) pounds. The 30' h. p. engine is a stock 
automobile engine, made by the Pennsylvania 
Automobile Co., and weighs 430 pounds'. Mr. 
Willoughby is now at work on another machine, 
which he calls the "Pelican," at Clementon, N. J. 
On the 15th of November Mr. Willoughby will 
leave with his machine for his winter home at 
Sewalls Point, Florida. 

Novice FHes First at Exhibition. 

George Schmitt, of 5 Royce St., Rutland. Vt., 
had a contract to fly and had never been in an 
aeroplane. The payment was contingent upon his 
actually flying. He did not get the machine 
ready in time to make any trial flights at all. 
He never knew even how to start the Elbridge 
engine, as he did not receive it until a day or 
two before the date of exhibition. He got his 
machine as.sembled at the exhibition grounds and 
just flew, and got paid. He bought the parts 
for the aeroplane from Witteman Brothers and 
assembled them himself. 



Flights in Kansas and Missouri. 

O. A. Mattingly, of Pittsburg. Kansas, has been 
making daily flights with his biplane on the prairies 
west of Pittsburg. Mr. Mattingly damaged his 
machine somewhat recently, but repaired "it and 
has become so proticient that he has agreed to tlv 
at the Ozark Four-State Exposition, at Joplin, Oct. 
8-17. 

He siays he intends to get thoroughly familiar 
with the "game," and then try for the St. Louis 
to New York prize. 

His machine has an original device of his own 
for lateral balancing. The machine and motot 
were built by the Holbrook Aero Supply Co., of 
Joplin. 

The De Chene-Sowers all-aluminum biplane, 
which is a Curtiss type in the main, with many 
original features, is making repeated flights at 
Joplin, and the makers are preparing to get be- 
fore the public with it. 

New York's Biggest Aeroplane Factory. 

That New York and vicinity has several plants 
for the making of aeroplanes is not so very gen- 
erally known, but the searcher for a machine can 
discover shops tucked away in lofts, in automobile 
garages and buildings which have sometime served 
a more earthy purpose. 

No one has seemed to pay much attention to 
the rumor that Capt. T. T. Lovelace, filibuster, 
■'admiral" of a South American one-boat navy, 
airship pilot, yachtsman, alligator hunter, show- 
man, aviator and balloonist, a "soldier of fortune," 
had joined with Fred. Thompson, who built Luna 
Park, the Hippodrome and has for some years 
been interested in the Fort George amusement park, 
in the building of aeroplanes on a big scale. 

On a high cliff overlooking the Harlem river 
and Spuyten Duyvil Creek, where Curtiss landed 
on his Albany-New York flight, is a huge dancing 
pavilion with a half dozen monoplanes in all 
stages of construction on its floor. The band's plat- 
form is now taken up with a work bench and 
tools. One of thesfe monoplanes is for Leo 
Stevens. Another building, measuring 150 feet in 




Stebbins and Geynet Triplane

length, has a line of shafting its entii'e distance, 
running planers, saws and all sorts of woodworking 
machinery. In still another building is a big 
lathe, drill presses, forges land other machine 
tools. Even a casting shop is being arranged. 
All the machines are run by electric motors. Off 
the big dancing room are other rooms with' 
draughting boards, work benches and an office. 

The buildings, for years allowed to go to rot 
and ruin, are being patched up and the roofs 
covered with tin ; storm-washed walks are being 
rebuilt and trees cleared off the grounds to make 
this historic spot a commonplace factory for the 
mlaking of flyers. 

Captain Lovelace was in charge of the last show 
the Aero Club of America had. Then he was at 
the Jamestown Exposition in the aeronautical 
department. From there he took an airship to 
Panama, which enterprise did not end in any 
ascents, owing to impossibility of making the gas 
there. He wias next heard of in London when 
his airship took fire at an exposition, and a 
young lady assistant was burned to death. After 
being with Wilbur Wright at Le Mans and Rome, 
he wias manager of the aerial department of the 
Humber Company in England. His first public 
appearance in flight was at the Doncastcr meet. 

Stevens Buys Aeroplane. 

Aeronaut Leo Stevens, who has been sailing and 
building balloons for miany years, has bought an 
aeroplane — two of 'em. 

That does not mean at all that ballooning is 
decadent, but that the aeronaut wiants merely a 
new sensation. Ballooning will always hold its own. 
In tills country the sport has increased in popu- 
larity instead of declining. 

Stevens has been considering the making of 
aeroplanes and has looked over the field and has 
now bought a 35 horse power monoplane built 
by the Lovelace-Thompson aeroplane and motot 
works. 

Hamilton Has Speed Marvel. 

On the Olli of Octolior. Chas. K. Hamilton began 
flying again after his accident at Pasadena. With- 
out preliminary runs of the 110 h. p. Christie en- 
gine, he started from the Aeronautical Society's 
shed and shot in the air almost instantly. Wil- 
liam Wurster, of the W. C. P. Co., swears his 
speed was 100 miles an hour. He says he timed 
him over the course, said to be 1^4 miles, but 
never officially measured, even by America's latest 
controlling organization, the National Council, in 
39 seconds. This figures out at IIG miles. Per- 
haps Brother Wurster was wrong, but. at any 
rate, everyone says he has more speed than any 
record yet, which means 70 miles an hour. 



Capf. WJlJotrghby's J^schine 



The machine is a straight Curtiss type, but built 
extra heavy, reinforced all through and guyed with 
big wires. New light Goodyear tires and rims 
have been put on. 




The Hamilton Engine. 

The Hamilton engine was designed by Walter 
Christie, who says there has been some misprint 
in regard to it. The bore is 4%x7 in. stroke. 
A. L. A. M. rating makes this 61 horse power. 
The makers rate the engine at 110 horse power 
at 1,500 r. p. m. In view of the length of the 
stroke this would seem' to be a conservative esti- 
mate. 

Coddington & Webb (Mangum Webb and C. C. 
Coddington) has leased a five-acre tract on Provi- 
dence road, Charlotte, N. C, and will establish 
an experimental station for manufacturing aero- 
planes. A contractor of Charlotte is proceeding 
with construction of timber building 150^40 and 
40x40 feet in size ; the company will also con- 
duct an aeroplane school. 

Dr. William Greene has made his first flight 
with his new cross-country aeroplane at Rochester. 



O. Chanute 111 in New York.

Vermont Man Builds Curtiss Type. 

C. C. Bonetto. of Passumiisic. Vt,. has built a 
Curtiss type biplaue from the information given 
iu AERONAimcs, and is using tlie raacliine fo"i- ex- 
liihition purposes. 

FROM PARACHUTE TO AEROPLANE. 

In tallving with a representative of Aeron'autics. 
Mr. Bonette said : "I have been in the hot air 
balloon line for the past IS years, with para- 
fhute work. I originated some very good features 
in this line. Including parachute from parachute 
act, which I did! for the first time at Plattsburg, 
X. y., in 1903. I had the aeroplane idea soon 
as the Wrights made flights, and decided to either 
Iniy or build one for exhibition purposes, as I 
could see that it was the coming attraction. I 
got prices on machines, and could see where I 



could save a liig auiuunt by building my own 
machine, which I did. I don't believe any ma- 
chine was ever built und^er more difticulties," than 
mine. After nine months of hard work, and lots 
of remodeling up to two weeks ago. I got a flier. 

"My machine is a Curtiss type, leaves the ground 
nicely, and is a bird in the air. I have an 
Elbridge 40 h. p. engine that is proving very 
satisfactory. I have a good offer for the winter 
with my machine and I want one engine man, and 
one experienced aviator: can you help me to find the 
two men? I want these men for six months, and 
by that time I hope to be able to drive my 
machine. Will you kindiy send me the addresses 
of one or two good) men ? 

"I use the Requa-Gibson 7 ft. by 4 ft. pro- 
peller. I consider these are the best propellers 
in the market."

M. B. Sellers May Fly in New York. 

M. B. Sellers, of Gralin, Ky.. who has boon 
doing such wonderful work in his flights with but 
a little over four horse power, has equipped his 
latest machine with wheels for starting. These 
rise automatically when the machine leaves the 
ground and allow the aeroplane to alight on the 
runners. Mr. Sellers" use of this acttially ante- 
dates the published accounts of the Farman and 
Antoinette flights, being used in a model in .Tune, 
1908. The use of the weight, as described hereto- 
fore fully in Aeronautics, has been done away 
with. Successful flights are now being made with 
a Bates 2-cylinder opposed rated 10 h. p. motor. 

Mr. Sellers hopes to come to Mineola soon and 
Show New Yorkers what can be done with a little 
bit of power. His work has been not to just fly — 
as almost any machine can do that — hut to de- 
velop the efliciency of surfaces and a propeller 
to a point where successful flight may be ob- 
tained with the minimum of power. 

Women Learn to Fly. 

Miss Blanche Scott, the young lady who drove 
an automobile across the continent, began her 
trials at flight with a Curtiss machine at Ham- 
mondsport on Sent. 20. After a few flights by 
Glenn Curtiss himself. Miss Scott was allowed 
to do some "gi'ass cutting" to get accustomed to 
the controls. After an hour of this she made a 
counle of short straightaway flia-hts. The rest 
of that week was a repetition of the lessons, with 
grass cutting and flights alternating. 

Mrs. F. Raiche, whose husband has endeavored 
to nstablish an aeroplane manufacturing business 
at Alineola, has made a nunilier of successful flights 
with a Curtiss type machine fitted with a Fox 
"De Luxe" motor. Previous attemnts at flights 
had been made by Raiche but his home-m'ade 
engine either fell to pieces or did not work. Then 
he got the Dean engine and the "Missus" tried the 
machine and
